[Partial trisomy (10pter leads to 10q21) and partial monosomy (21pter leads to 21q21) due to a reciprocal balanced familial translocation (10;21)(q21;q21) (author's transl)].

A newborn infant is reported with a karyotype showing a partial trisomy 10 (10pter leads to 10q21) and a partial monosomy 21 (21pter leads to 21q21) due to a reciprocal balanced familial translocation t(10;21)(q21;q21). This is the first case of partial trisomy 10 for the segment 10pter leads to 10q21.

[The cerebro-oculo-facio-skeletal syndrome].

A further case of the cerebro-oculo-facio skeletal syndrome is described. The child, the first of healthy parents with no significant family history, died on the 4th day of life because of renal failure and respiratory difficulties. The dysmorphic features were microcephaly, microphthalmia, high nasal bridge, lax skin with a prominent skin fold extending below the eyes, large upper lip, fixed flexion deformities of the limbs, short fingers with campodactyly, talus valgus and longitudinal plantar groove. At autopsy there was renal agenesis, a hypoplastic bladder, bilateral cataract with atrophy of the iris and retina. The relationship between Potter's syndrome and other oculo renal syndromes are discussed. The diagnosis is important because this syndrome is inherited as an autosomal recessive.

[Carpenter's syndrome].

A newborn boy presented with an acrocephaly characterized by a coronal craniosynostoses, open sagittal sutures and abnormally high and straight forehead. He was the only child of young, unrelated, healthy parents; there was no familial history of dysmorphy. Facial asymmetry was important and associated with posterior cleft palate, syndactylia of the tips and polydactylia of feet, due to a splitting of the first metatarsus. The child also had a congenital heart disease, like in half of the 15 published cases. In older children, mental retardation is usually observed, often associated with obesity and hypogonadism. Polydactylia permitted to exclude Apert's acrocephalosyndactylia in which there is a normal number of finger arms and which seems to be a dominant mutation, while the transmission of Carpenter's syndrome appears autosomal recessive, thus requiring restrictive genetic counselling.
