    Notes: Summary Two new cases of Krabbe disease were diagnosed prenatally in a family with two previous affected children. The activity of galactosylceramide-β-galactosidase was virtually absent in cultured amniotic cells. The prenatal diagnosis was confirmed enzymatically in cultured fibroblasts, brain, and visceral organs. Light and electron microscopy studies in both fetuses, 20 and 23 weeks of gestational age respectively, revealed the presence of typical globoid cells in the white matter of the spinal cord. Specific inclusions were also found in the brain stem and in peripheral nerves of the second fetus. A comparison with other Krabbe disease fetuses described in the literature contributes to the consensus that abnormal morphological findings can be expected in particular in the most actively myelinating areas of the nervous system. Although most of the cells containing the specific melusions are probably non-glial in nature, some of them could represent myelination glia.

    Description / Table of Contents: Résumé Les auteurs décrivent une grande famille où sur 4 générations, 15 sujects sont atteints de dysplasie des crêtes épidermiques digitales, palmaires et plantaires. Dans cette famille, l'anomalie se transmet visiblement sur le mode dominant autosomique avec pénétrance complète et expressivité variable.
    Notes: Summary A large family is described where 15 individuals on 4 generations are affected with a dysplasia of the digital, palmar and plantar epidermal ridges. In this family, the anomaly is transmitted according to the autosomal dominant mode of inheritance with complete penetrance and variable expressivity.

    Description / Table of Contents: Résumé Nous croyons avoir isolé un nouveau syndrome dysmorphique dont les caractères sont les suivants: 1. dysplasie des crêtes épidermiques, particulièrement à l'extrémité des doigts; 2. hypoplasie de la pulpe digitale; 3. dépressions transversales des ongles (dysplasie unguéale); 4. crevasses douloureuses et passagères de la pulpe digitale; transmission héréditaire dominante autosomique. Si ce groupement de symptomes devait se retrouver lors de l'étude d'autres familles, nous proposerions de nommer ce syndrome dysplasie apicale des doigts.
    Abstract: Zusammenfassung Ein neues dysmorphisches Syndrom ist hier beschrieben worden, das folgendermaßen zu charakterisieren ist: 1. Dysplasie der Hautleisten; 2. Hypoplasie der Polsterung der Fingerbeeren; 3. Querfurchen auf den Nägeln (Nageldysplasie); 4. vorübergehende schmerzhafte Risse auf den Fingerbeeren; 5. autosomal dominante Vererbung. Wenn dieses Syndrom auch in anderen Familien vorkommt, möchten wir die Bezeichnung “Apikale Dysplasie der Finger” vorschlagen.
    Notes: Summary A new dysmorphic syndrome has apparently been recognized consisting of the following features: 1. dysplasia of the epidermal ridges; 2. hypoplasia of the fingerpads; 3. transverse hollows of the nails (nail dysplasia); 4. transitory painful chaps of the fingerpads; 5. autosomal dominant transmission. If this group of features would also be present in other families, the syndrome could be called apical dysplasia of the fingers.

    Description / Table of Contents: Résumé L'existence de deux populations cellulaires, l'une HGPRT+ et l'autre HGPRT- a pu être démontrée en cultures de fibroblastes à partir de biopsies cutanées chez la soeur, la mère et une soeur de la mère d'un patient atteint du syndrome de Lesch-Nyhan. Ce but est aisément atteint en réalisant une sélection biochimique des cellules mutantes par la 8-azaguanine avant l'autoradiographie des cultures incubées avec l'3H-hypoxanthine; parallèlement les cellules normales sont isolées dans le milieu HAT. Ceci nous paraît être une méthode sûre et relativement peu compliquée, de diagnostiquer dans les familles atteintes, les femmes hétérozygotes dont la descendance mâle court un risque important de syndrome de Lesch-Nyhan. C'est précisément le cas de la jeune soeur du patient, dont toute grossesse éventuelle doit être suivie dès le début et exige une détection prénatale de cette affection.
    Abstract: Zusammenfassung Zwei unterschiedliche Zellpopulationen (HGPRT+und HGPRT-) wurden aus den Hautfibroblasten einer Schwester, der Mutter und einer Tante mütterlicherseits eines Patienten mit X-chromosomalem Lesch-Nyhan-Syndrom isoliert. Das Ergebnis wurde mit Hilfe biochemischer Selektion vor der Autoradiographie mit 3H-Hypoxanthin erzielt. Mutierte Zellen wurden in einem Nährmedium mit 8-Azaguanin isoliert, während normale Zellen im HAT-Medium wuchsen. Diese erwies sich als eine einfache und zuverlässige Methode zur Erkennung von weiblichen Heterozygoten in Familien von Patienten mit Lesch-Nyhan-Syndrom. Wegen des hohen Risikos des Auftretens des Syndroms bei männlichen Nachkommen ist die pränatale Diagnostik bei weiblichen Trägern indiziert. In diesem Fall gilt das für die 12jährige Schwester des Probanden.
    Notes: Summary Two distinct cell populations (the first HGPRT+, the other HGPRT-) were isolated in skin fibroblasts cultures from a sister, the mother and a maternal aunt of a patient with Lesch-Nyhan syndrome, an X-linked disorder. This result was achieved by means of a biochemical selection prior to autoradiography with 3H-hypoxanthine. Mutant cells were isolated in a medium containing 8-azaguanine, while normal cells were grown in HAT medium. This proved to be an easy and reliable method for detecting female heterozygotes in families where a patient with Lesch-Nyhan syndrome had been observed. A pre-pregnancy diagnosis of these female carriers is advisable because of the high probability of a full-blown syndrome in their male descendants. This was particularly the case of the 12 years old proband's sister in the family studied here.

    Notes: Summary Two sibs with a rare phenotype of oligodactyly with metacarpal, carpal, radioulnar, and metatarsal synostoses and shortening of the forearms were born of healthy parents. Genetic counselling with regard to future children of one of these sibs was given on the assumption of an autosomal recessive inheritance, which is highly probable, judging from the other rare familial cases found in the literature.
