VOLLMAN, M.D., Head, Section on Obstetrics, Perinatal Research Branch, National Institute of Neurological Diseases and Stroke, National Institutes of Health, Bethesda, Md. 20014, U.S.A. iv CLASSIC PAPERS ON DOWN’S SYNDROME With a few, well-chosen words J. Langdon H. Down, in 1866, described the clinical picture and the diagnostic criteria of the syndrome that now carries his name. He saw that the condition was “always congenital” and that the patient’s “life expectancy is far below the average.” He, therefore, discounted any possible etiologic association with birthtrauma, accident, medication, malnutrition or “maternal imagination.” But he was caught in the philosophical speculations of his time on the descendence of the human races when he postulated that mongolism is the “result of degeneracy among mankind.” In the same year E. Seguin differentiated “furfuracious cretinism” from endemic cretinism, a classification which he had already presented in an earlier publication (1846). It may be assumed that “furfuracious cretinism” is identical with Down’s syndrome. P. J. Waardenburg suggested in a study on the genetics of the human eye that mongolism could be due to a “chromosomal aberration”—“a chromosomal deficiency through non-disjunction” or a “translocation,” a hypothesis which was verified 27 years later through J. Lejeune’s karyotype studies. London Hospital. Clinical Lectures and Reports 3: 259—62, 1866. OBSERVATIONS ON AN ETHNIC CLASSIFICATION OF IDIOTS By J. Langdon H. Down, M.D., Lond. “Those who have given any attention to congenital mental lesions, must have been frequently puzzled how to arrange, in any satisfactory way, the different classes of this defect which may have come under their observation. Nor will the difficulty be lessened by an appeal to what has been written on the subject. The systems of classification are generally so vague and artificial, that, not only do they assist but feebly, in any mental arrangement of the phenomena which are presented, but they completely fail in exerting any practical influence on the subject. The medical practitioner who may be consulted in any given case, has, perhaps in a very early condition of the child’s life, to give an opinion on points of vital importance as to the present condition and probable future of the little one. Moreover, he may be pressed as to the question, whether the supposed defect dates from any cause subsequent to the birth or not. Has the nurse dosed the child with opium? Has the little one met with any accident? Has the instrumental interference which maternal safety demanded, been the cause of what seems to the anxious parents, a vacant future? Can it be that when away from the family attendant the calomel powders were judiciously prescribed? Can, in fact, the strange anomalies which the child presents, be attributed to the nu- merous causes which maternal solicitude conjures to the imagination, in order to account for a condition, for which any cause is sought, rather than hereditary taint or parental influence. Will the systems of classifica- tion, either all together, or any one of them, assist the medical adviser in the opinion he is to present, or the suggestions which he is to tender to the anxious parent? I think that they will entirely fail him in the matter, and that he will have in many cases to make a guarded diagnosis and prognosis, so guarded, in fact, as to be almost valueless, or to venture an authoritative assertion which the future may perhaps confirm. I have for some time had my attention directed to the possibility of making a classification of the feeble-minded, by arranging them around various ethnic standards, —in other words, framing a natural system to supplement the information to be derived by an inquiry into the history of the case. I have been able to find among the large number of idiots and imbeciles which come under my observation, both at Earlswood and the out-patient department of the Hospital, that a considerable portion can be fairly referred to one of the great divisions of the human family other than the class from which they have sprung. Of course, there are numerous repre- sentatives of the great Caucasian family. Several well-marked examples 2 of the Ethiopian variety have come under my notice, presenting the characteristic malar bones, the prominent eyes, the puffy lips, and re- treating chin. The woolly hair has also been present, although not always black, nor has the skin acquired pigmentary deposit. They have been specimens of white negrocs, although of European descent. Some arrange themselves around the Malay variety, and present in their soft, black, curly hair, their prominent upper jaws and capacious mouths, types of the family which people the South Sea Islands. Nor have there been wanting the analogues of the people who with shortened foreheads, prominent cheeks, deep-set eyes, and slightly apish nose, originally inhabited the American Continent. The great Mongolian family has numerous representatives, and it is to this division, I wish, in this paper, to call special attention. A very large_ 5 number of congenital idiots are typical Mongols. So marked is this, that i when placed side by side, it is difficult to believe that the specimens compared are not children of the same parents. The number of idiots who arrange themselves around the Mongolian type is so great, and they present such a close resemblance to one another in mental power, that I shall describe an idiot member of this racial division, selected from the large number that have fallen under my observation. The hair is not black, as in the real Mongol, but of a brownish colour, straight and scanty. The face is flat and broad, and destitute of prom- inence. The cheeks are roundish, and extended laterally. The eyes are obliquely placed, and the internal canthi more than normally distant from one another. The palpebral fissure is very narrow. The forehead is wrinkled transversely from the constant assistance which the levatores palpebrarum derive from the occipitofrontalis muscle in the opening of the eyes. The lips are large and thick with transverse fissures. The tongue is long, thick, and is much roughened. The nose is small. The skin has a slight dirty yellowish tinge, and is deficient in elasticity, giving the ap- pearance of being too large for the body. The boy’s aspect is such that it is difficult to realize that he is the child of Europeans, but so frequently are these characters presented, that there can be no doubt that these ethnic features are the result of degeneration. The Mongolian type of idiocy occurs in more than ten per cent of the cases which are presented to me. They are always congenital idiots, and never result from accidents after uterine life. They are, for the most part, instances of degeneracy arising from tuberculosis in the parents. They are cases which very much repay judicious treatment. They require highly azotised food with a considerable amount of oleaginous material. They have considerable power of imitation, even bordering on being mimics. They are humorous, and a lively sense of the ridiculous often colours their mimicry. This faculty of imitation may be cultivated to a very great extent, and a practical direction given to the results obtained. They are usually able to speak; the speech is thick and indistinct, but may be improved very greatly by a well—directed scheme of tongue gymnastics. ‘v’ 3 i The co-ordinating faculty is abnormal, but not so defective that it cannot be greatly strengthened. By systematic training, considerable manipula- tive power may be obtained. The circulation is feeble, and whatever advance is made intellectually in the summer, some amount of retrogression may be expected in the winter. Their mental and physical capabilities are, in fact, directly as the tempera- ture. The improvement which training effects in them is greatly in excess of what would be predicated if one did not know the characteristics of the type. The life expectancy, however, is far below the average, and the tendency is to the tuberculosis, which I believe to be the hereditary origin of the degeneracy. Apart from the practical bearing of this attempt at an ethnic classifica— tion, considerable philosophical interest attaches to it. The tendency in the present day is to reject the opinion that the various races are merely varieties of the human family having a common origin, and to insist that climatic, or other influences, are insufficient to account for the different types of man. Here, however, we have examples of retrogression, or at all events, of departure from one type and the assumption of the character- istics of another. If these great racial divisions are fixed and definite, how comes it that disease is able to break down the barrier, and to simulate so closely the features of the members of another division. I cannot but think that the observations which I have recorded, are indications that the differences in the races are not specific but variable. These examples of the result of degeneracy among mankind, appear to me to furnish some arguments in favour of the unity of the human species.” IDIOCY: and ITS TREATMENT by the PHYSIOLOGICAL METHOD by EDWARD SEGUIN, MD. New York William Wood & Co., 61 Walker Street 1866 V”?— Page 43: “Endemic idiocy is interwoven with alpine 0r lowland cretinism and bronchocele, producing at birth the cretin—idiot, in youth the cretin- imbecile, and after puberty the cretin (simplex), able to procreate his like. Thus cretinism, besides its apparent geological connexion or origin, is hereditary, like scrofula; a taint in the blood, preparing children for idiocy or imbecility, according to the age of its invasion. This alpine cretinism is due to locality and to intermarriage, and it is never isolated; it affects the skin with a bistre or maroon color. Its action does not cease Page 44: after having produced idiocy, for if its victim be put in a locality where cretinism will aggravate, idiocy will do the same; and if placed in circum— stances of climate, of hygiene, of exercise, where cretinism may improve, idiocy will also improve, and shall become more amenable to the physio- logical treatment, as the labors and devotion of Guggenbfil have abun- dantly proved. The low-land cretinism of Belgium, of Virginia, etc., with its discrete goitre, its grey and dirty straw—colored skin, bears the same relation to idiocy and imbecility as the more extensive alpine variety. SO does the furfuraceous cretinism, with its milk—white, rosy, and peeling skin; with its shortcomings of all the integuments, which give an unfinished aspect to the truncated fingers and nose; with its cracked lips and tongue; with its red, ectropic conjunctiva, coming out to supply the curtailed skin at the margin of the lids. Page 381 : As cretinism affects evidently the skin, we cannot dissever from it a form of idiocy in which the skin is furfuraceous. Our incomplete studies do not permit of its actual classification; but it is better to leave things by themselves, than to force them into classes which have their foundation only on paper.” DAS MENSCHLICHE AUGE UND SEINE ERBANLAGEN VON Dr. P. J. Waardenburg Augenarzt in Arnhem “i: Martinus ij hoff 1932 Mongolismus (Mongoloide Idiotie)* Page 47: “Ich moechte die Cytologen anregen zu untersuchen, ob es nicht moeglich waere, dass hier beim Menschen ein Beispiel einer bestimmten Chromosomenaberration vorlaege. Warum sollte dieselbe auch nicht wohl einmal beim Menschen vorkommen koennen, und warum waere es dann nicht moeglich, dass sie, wenn sie nicht letal wirkt, eine eingreifende Konstitutionsanomalie verursachen wuerde: Man sollte einmal beim Mongolismus untersuchen, ob hier vielleicht ‘chromosomal deficiency’ durch ‘non—disjunction’ oder das umgekehrte ‘chromosomal duplication’ vorliegt. Es ist natuerlich auch denkbar, dass nur eine Stoerung von Chromosomen—Teilen (Chromomeren): eine ‘sectional deficiency’ durch ‘translocation’ oder umgekehrt eine ‘sectional duplication’ vorliegt; das waere dann weniger leicht cytologisch zu beweisen. Meine Hypothese hat jedenfalls den Vorteil, dass sie kontrollierbar Page 48: ist und dass sie auch den evtl. Einfluss des Alters der Frau erklaeren wuerde . . .” P. J. Waardenburg, Das menschliche Auge und seine Erbanlagen, 1932. (Translation) Mongolism (Mongoloid Idiocy) I should like to suggest to the cytologists that they investigate if this condition may be an example of a definite chromosomal aberration in man. Why could a chromosomal aberration not occur in man, too, if it were not lethal; why could such an aberration not produce a generalized constitu- tional abnormality. One should study mongolism for its possible associa- tion with a ‘chromosomal deficiency’ through ‘non-disjunction’, or the reverse, ‘chromosomal duplication’. Of course, it is possible, too, that there is only a disturbance of part of the chromosomes (chromomeres), a ‘sectional deficiency’ through translocation, or the reverse, a ‘sectional duplication’. This situation would be more difficult to prove cytologically. At any rate, my hypothesis has the advantage that it can be tested. It would, in addition, explain the potential effect of the maternal age. * Reprinted with permission of the author. 602 ACADEMIE DES SCIENCES. SEANCE DU 26 JANVIER 1959. GENETIQUE. — Les chromosome: humains en culture de tissus. Note de M. Jénfine LEJEUNE, M"' MARTIN! GAU’I'HIEB et M. Rumoxn TURPIN, présentée par M. Léon Binel. Une technique de culture de fibroblastes a court terme permet d’étudier systema- tiquemenl les [.6 chromosomes humains. La presence, chez. la Femme, de qualre lrés relils chromosomes 3 cenlromére quasi terminal, el de cinq du méme type chez 'llomme, aulorise un diagnostic du sexe chromosomique. Chez trois garcons mon— goliens, ce critére a élé mis en échec du {ail de la presence de 47 chromosomes. Technique de culture. — Un fragment de tissu conjonctif non adipeux (fascia lata) est prélevé aseptiquement et cultivé sur lamelle micros- copique selon la technique habituelle. Apres suppression de l’explant on obtient une couche monocellulairc sur la lamelle. L’éclatement in situ des ccllules par choc hypotonique, suivi de fixation et du séchage a l’air libre (Rothfelds et Siminovitch) (‘), permet une excellente dispersion des chromosomes. La coloration utilisée est du type Feulgen, modifie’. Technique d’examen. — Les preparations sont photographiées sur film « microfile Kodak » (grossissement X 375 sur le film; microscope « Leitz » immersion X 90, oculaire périplan X' 10, chambre « Mikas » 1/3),et secon- «lairement, le cliché est agrandi huit fois pour obtenir un grandissement de X 3 000 sur l’épreuve. Les comptages sur épreuvcs sont ensuite vérifiés par observation visuelle en cas de dillicultés d’interprétation. Toutes les preparations étudiées ont moins d’un mois de culture. Au- dela du septiéme repiquage in vitro, on constate parfois en ellet une varié- gation du nombre chromosomique (tétraploidie, aneuploidie) alors que ce nombre est au contraire trés constant lors des tous premiers passages. Observations. — Les examens pratiqués sur plusieurs lignées cellulaires parallelcs pour chaque indiviilu (lonnent des résultats entiérement eohé- rents. Chez quatre garcons normaux, un garcon malformé (absence de main), un garcon atteint d’ostéopsathyrose et chez deux filles normales, le nombre diploide normal de 46 a été retrouvé. 10 Chcz tous les garcons cinq trés petits chromosomes ont été observés, alors que chez les deux filles, quatre chromosomes seulement de ce type sont décclables. Lc chromosome y, ainsi que l’ont supposé Ford et Jacobs (2), est probablcment l’un d’entre eux. Le diagnostic individuel du chromosome 1:, présent é double exemplaire chez Ia chmc, est faisable chez l’Homme aprés elimination des difl'érentes paires possibles. Cependant cette recherche n’est réalisable que sur quelque's cellules exceptionnellement claires. Chez trois garcons mongoliens, 1e nombre chromosomique trouvé est de 47 sur différentes préparations, pour chacun des trois individ‘us. Dans les trois cas 1e diagnostic du sexe a été rendu impossible du fait de la présence d’un trés petit chromosome supplémcntaire qu’on ne peut diflérencier des cinq petits éléments presque télocentriques, normalement rencontrés chez l’Homme.

In these three cases, the diagnosis of the sex was impossible due to the presence of a very small, supplementary chromosome which cannot be differentiated from the 5 small telocentric elements which are normally present in the male. The significance of this observation, together with the systematic study of other constitutional diseases, will be pursued in current research. 12 ACADEM IE DES SCIENCES.

(Translation) Study of the somatic chromosomes of 9 mongoloid children. The fibroblast cultures from 9 mongoloid children reveal the presence of 47 chromosomes. The supernumerary chromosome is a small telocentric body. A hypothesis of the chromosomal determination of mongolism is presented. Studying the mitoses of fibroblasts in tissue cultures from 9 mongoloid children, we regularly found 47 chromosomes. The observations from these 9 cases (5 boys and 4 girls) are presented in the table. The number of cells analyzed in each case may seem to be small. In this table, only those chromosomal pictures are reported that require a minimum of interpretation. An apparent variation in the number of the chromosomes in ”doubtful” cells, i.e., cells in which each single chromosome cannot be identified definitely, has been reported by numerous authors. We think that this phenomenon does not correspond to a cytologic reality but that it simply reflects the difficulties of a delicate technique. It seems logical to us to prefer a small number of definite counts (“perfect” cells of the table) to an accumulation of doubtful observations, the statistical variance of which depends upon the imprecision of the observations. The analysis of the chromosomal sets of the “perfect” cells discloses the presence of 6 small, telocentric bodies in the mongoloid boys (instead of 5 in the normal male) and of 5 small teloecntrics in the mongoloid girls (instead of 4 in the normal female). The “perfect” cells of non-mongoloid individuals never present these characteristics. We, therefore, legitimately conclude that in the mon— goloids a small, telocentric, supernumerary chromosome exists which accounts for the abnormal number of 47. DISCUSSION. To explain the whole set of these observations, the hypothesis of the non-disjunction at the meiosis of a pair of small, teloecntrics is proposed. We know that in Drosophila non-disjunction is strongly influenced by maternal aging. Therefore, such a mechanism could account for the increase in the rate of mongolism with the advancing age of the mother. However, we cannot affirm that the small, teloecntric, supernumerary body is definitely a normal chromosome because, at the present time, we cannot discount the possiblity that it may be a fragment resulting from another type of aberration.

Letters To The Editor “MONGOLISM” “Sir,—It has long been recognised that the terms “mongolian idiocy”, “mongolism”, “mongoloid”, &c., as applied to a specific type Of mental deficiency, have misleading connotations. The occurrence Of this anomaly among Europeans and their descendants is not related to the segregation of genes derived from Asians; its appearance among members of Asian populations suggests such ambiguous designations as “mongol Mon- goloid”; and the increasing participation of Chinese and Japanese in- vestigators in the study of the condition imposes on them the use of an embarrassing term. We urge, therefore, that the expressions which imply a racial aspect of the condition be no longer used. Some of the undersigned are inclined to replace the term “mongolism” by such designations as “Langdon—Down anomaly”, or “Down’s syn- drome or anomaly” or “congenital aeromicria”. Several others believe that this is an appropriate time to introduce the term “trisomy 21 anomaly” which would include cases of simple trisomy as well as trans- locations. It is hoped that agreement on a specific phrase will soon crys- tallise if once the term “ mongolism” has been abandoned.” GORDON ALLEN Bethesda, Maryland. C. E. BENDA Waverly, Massachusetts. J. A.

PREFACE This reference biblography of publications on Down’s syndrome is selected from a review of the world literature. The criteria for inclusion of a publication in the bibliography are: 1. Originality of observation reported; 2. Description and analysis of a representative series of cases; 3. Presentation of a new hypothesis on the etiology of Down’s syn- drome; 4. Review of pertinent publications. The original publications have all been reviewed. Entries indicated by (BIBL) contain 20 or more references which may not be reprinted in this reference bibliography. Five other extensive bibliographies on Down’s syndrome have been published recently by Brousseau, Benda, Stiles, Zellweger, and Penrose. Due to the special interests of the authors, their bibliographies overlap only in part (see Table I). At the present time it may be estimated that of the important publications on Down’s syndrome, 10 per cent were pub- lished in 1900 or before, 25 per cent between 1901 and 1950, and 65 per cent appeared in 1951 and later.

()TA’S basic function is to help legislative policy— makers anticipate and plan for the consequences oftechnologieal changes and to examine the many ways. expected and unexpected. in which technology affects people‘s lives. The assessment of technology calls for exploration of the physical, biological. economic, social. and political impacts that can result from applications of scientific knowledge. ()TA provides Congress with in- dependent and timely information about the potential effects—both benefi— cial and harmful—of technological applications. Requests for studies are made by chairmen of standing committees of the House of Representatives or Senate; by the Technology Assessment Board, the governing body of()TA: or by the Director ofOTA in consultation with the Board. The Technology Assessment Board is composed of six members of the House. six members of the Senate. and the OTA Director. who is a non— voting member. OTA has studies under way in nine program areas: energy and materi— als; industry, technology. and employment; international security and com— merce; biological applications; food and renewable resources: health: telecommunication and computing technologies: oceans and environment: and science. education. and transportation.
