We report on a Brazilian boy (F = 1/16) born to consanguineous parents and presenting with typical Aarskog syndrome. Genetic aspects and phenotypic manifestations of this patient are compared with those of the (X-linked) Aarskog syndrome and with the autosomal recessive faciodigitogenital syndrome.
We describe 2 Brazilian sisters with a combination of clinical signs strongly suggesting a new autosomal recessive MCA/MR syndrome.
We report on 5 unrelated Brazilian children with short stature, Robin sequence, cleft mandible, pre/postaxial hand anomalies, and clubfoot. Genetic aspects and phenotypic manifestations are compared with those of previous reports of acrofacial dysostoses and with other Robin sequence syndromes. We suspect that these patients present a previously undescribed autosomal recessive syndrome.
The syndrome: We describe 3 Brazilian brothers presenting a cluster of signs strongly suggesting a "new" MCA/MR syndrome. The main clinical signs include short stature, microbrachycephaly, mental retardation, palpebral ptosis, coloboma of iris and retina, nystagmus, strabismus, and cleft lip/palate. This is either an autosomal or X-linked recessive trait.
We report on a Brazilian girl, born to consanguineous parents and presenting a multiple congenital anomaly (MCA) syndrome, mainly characterized by blepharophimosis, cleft palate, and arachnodactyly. The clinical aspects involving this patient suggest an apparently undescribed "new" autosomal recessive syndrome.
We report on two unrelated Brazilian girls born to normal and nonconsanguineous parents and presenting ectodermal dysplasia, ectrodactyly, clefting, tear duct anomalies, and micro/anophthalmia. The clinical picture presented by these patients suggests the diagnosis of Goltz-Gorlin (Focal dermal hypoplasia) syndrome and EEC syndrome.

We report on a Brazilian woman with mandibulofacial dysostosis, cleft lip/palate, vertebral anomalies, abnormally modeled femora, and bilateral tibial agenesis. The clinical aspects involving this patient strongly suggest an unreported condition. Clinical and genetic aspects are discussed.
We report on a Brazilian boy with ectrodactyly, cleft lip/palate, and abnormal pinnae. The clinical aspects involving this patient strongly suggest those reported by Lewis and Pashayan in 1981. Clinical and genetic aspects are discussed.
We report on 4 persons in a 3-generation Brazilian family presenting the nail-patella syndrome. Cleft lip/palate in one patient and antecubital pterygium in 3 of the reported patients are unusual findings related to this condition.
We report on 3 persons in a 3-generation Brazilian family affected with complex limb defects. The spectrum of limb anomalies ranged from isolated toe syndactyly to severe bilateral tibial aplasia. Radioulnar synostosis was present in 2 of the 3 patients. Clinical and genetic aspects are discussed.
We report on 4 new patients with acheiropodia ("the handless and footless families of Brazil"). This autosomal recessive condition involves all 4 limbs with a well-defined pattern of defects. Two of the patients described here had a small bone fragment in the upper stumps (Bohomoletz bone), an uncommon finding in acheiropodia.
We report on a Brazilian family with 11 affected patients through 4 generations presenting the Rapp-Hodgkin syndrome. The main clinical findings in different patients ranged from isolated trichodysplasia (sparse, brittle, and dry hair) to ectodermal dysplasia (1-2-3-4), cleft palate, tear duct anomaly, and minor limb anomalies. Clinical and genetic aspects concerning this condition are discussed.
We report on 3 Brazilian brothers born to normal consanguineous parents (F = 1/16) and presenting ectodermal dysplasia, cleft lip/palate, mental retardation, syndactyly of fingers 2-3, accessory nipples, and ear anomalies. The similarities of these 3 brothers to previously reported cases and the pattern of inheritance are discussed.
We report on 20 Brazilian patients (11 sporadic and 9 familial cases) with the ectrodactyly, ectodermal dysplasia, clefting syndrome (EEC syndrome). Genetic aspects, clinical manifestations, and differential diagnosis of the syndromes involving ectodermal dysplasia/limb anomalies and cleft lip/palate are discussed.
We report a 6-month-old boy, born of consanguineous (first-cousin) parents (F = 1/16) presenting microbrachycephaly, wide forehead, marked hypertelorism, broad nose with a midline groove with a bilateral small "blind dimple" in each side, hypospadias, syndactyly between fingers 3 and 4, broad thumbs, and halluces. This association of anomalies suggests the diagnosis of a "new" type of acro-fronto-facio-nasal dysostosis. Normal chromosomes, parental consanguinity, and familial occurrence suggest autosomal recessive inheritance.
We report on a Brazilian child with postaxial acrofacial dysostosis (AFD)-type Genée-Wiedemann. Clinical and genetic aspects of the postaxial acrofacial dysostoses are discussed.
We report on a Brazilian girl, born to a diabetic mother, and presenting with atypical pre/postaxial acrofacial dysostosis, nosologically related to the Genée-Wiedemann syndrome. Clinical and genetic aspects of this acrofacial dysostosis and its relationship to diabetic embryopathy are discussed.
