Partial trisomy 6q: case report with necropsy findings.

A male infant with partial trisomy 6q is described. This patient shares features with 12 previously reported cases including hypertelorism, cleft soft palate, bow shaped mouth, micrognathia, short, laterally webbed neck, clubbing of hands and feet, syndactyly, and growth retardation. In addition, visceral anomalies less frequently reported are described. These observations may extend the phenot...

Report of a Case with Trisomy 9 Mosaicism

Trisomy 9 is a rare chromosome disorder with high neonatal mortality. It is often seen in mosaic form. Most patients who survive are severely mentally retarded. The main features of this syndrome are "bulbous" nose, microphthalmia, dislocated limbs, and other anomalies of skeletal, cardiac, genitourinary, and central nervous system. Most patients have developmental and cognitive impairment. Pat...

Partial trisomy 12q: report of a case and review.

A malformed male infant with pure partial trisomy 12q (q24.1 leads to qter), resulting from an unbalanced segregation of a paternal balanced translocation t(2;12)(q37;q24.1), is described. The cytogenetic and clinical abnormalities of the proband are compared with those of four previously reported cases of partial trisomy 12q, two of which also appear to have pure trisomy of segment 12q24.1 lea...
