Orodigitofacial syndromes type I and II: clinical and surgical studies.

Eleven patients were followed at the multidisciplinary facial cleft department from 1963 to 1993. Nine had orodigitofacial (ODF) I syndrome (Papillon-Leage, 1954) and two had ODF II syndrome (Mohr, 1941). The authors observed seven median clefts of the upper lip, eight atypical cleft palates, nine lingual tumors, ten polylobed tongues, four ankyloglossia. All vestibular frenula were hypertrophied. Facial analysis showed five facial hypertelorisms, eight epicanthal folds, ten anomalies of the forehead. Nasal anomalies were constant with ten alar hypoplasia and four nasal curves. Syndactyly was the most frequent anomaly of the hand. Seven patients were mentally retarded. Transmission of ODF I is by X-linked dominant variable expression; ODF II is autosomal recessive. The difference in transmission means a precise diagnosis is necessary. Bilateral duplication of the great toe is characteristic of type II, but not pathognomonic. Hair and cutaneous anomalies suggest type I. The authors proposed a surgical treatment involving three operating steps.

Prenatal diagnosis of PIBIDS.

In a well-documented PIBIDS family, two investigations of DNA excision repair showed a severe defect in lymphocytes from the index case (residual repair activities were 10.6-12.1 per cent). The values for the mother, father, and sister were within the normal range when compared with a healthy control. In the pregnant mother, a prenatal diagnosis of PIBIDS was made by measuring UV-induced unscheduled DNA synthesis in cultivated amniotic fluid cells. Results ranged between 12.5 and 26.1 per cent depending on the UV doses applied and were consistent with an affected fetus. The parents opted for a termination of pregnancy. Following a therapeutic abortion, fetal skin fibroblasts were tested and showed a severe DNA excision-repair defect of 9.2-13.5 per cent of residual activity.

Trisomy 16q23----qter arising from a maternal t(13;16)(p12;q23): case report and evidence of the reciprocal balanced maternal rearrangement by the Ag-NOR technique.

We describe a female new-born with partial trisomy of the long arm of chromosome 16. The chromosome anomaly was the result of an unbalanced segregation of a maternal translocation t(13;16)(p12;q23). Dynamic (RBG, GBG) banding and the Ag-NOR technique ascertained the reciprocal balanced maternal translocation between the 16q23----qter and 13q12----pter segments because nucleolar organizers were present on the tip of long arms of the derivative 16 maternal chromosome. As monosomy 13p has little or no deleterious effect we consider our case as exhibiting the phenotype of trisomy 16q23----qter free from any monosomic feature. Clinical effects are of less consequence as compared with previously published cases of partial trisomy 16q.

[Stickler's syndrome or hereditary progressive arthro-ophthalmopathy].

A case of Stickler's syndrome is reported. This syndrome associates eye defects, craniofacial and musculo-skeletal abnormalities, sensori-neural hearing loss and mitral-valve prolapse. It is an autosomal dominant disorder probably resulting from a connective tissue dysplasia. There is a major risk for the occurrence of serious ocular problems (blindness), and ophthalmologic follow-up has to be performed on affected persons and relatives in order to improve the long term prognosis.

[Familial true hermaphroditism (apropos of 2 families)].

The authors report the cases of two new families of true hermaphroditism (4 cases) defined by the coexistence of both testicular and ovarian tissues. Exceptionally the disease presents a familial recurrence: only 8 families have been reported in the literature. When the study is done HY antigen is always increased in patients with true hermaphroditism and sometimes slightly increased in their mothers who are phenotypically normal.

Prenatal diagnosis of thrombocytopenia-absent radius syndrome.

Thrombocytopenia-absent radius (TAR) syndrome is an autosomal-recessive disorder characterized by a thrombocytopenia and a bilateral radial aplasia with normal thumbs. Only TAR syndrome, out of diseases which may present with radial aplasia, typically has normal thumbs. The prenatal diagnosis is rarely made. We report two observations of TAR syndrome diagnosed in utero in the sibling. The malposition of fetal hands detectable as soon as 11 weeks of gestation requires careful search for longitudinal limb defect of the forearm, especially radial ray defect. The radial aplasia is associated with numerous causes (chromosomal, teratogenic, genetic, multifactorial). The determination of fetal hematologic values revealing a thrombocytopenia allows the prenatal diagnosis of the index case of TAR syndrome.
