- Abstract
Duplication of 6q24 leads to 6qter was identified by GTG banding in an infant girl whose father was a balanced translocation carrier 46,XY,t(3;6)(p26 leads to q2402). At birth and at 4 mo she had proportionate short stature, microcephaly, asymmetric micrognathia, bow-shaped upper vermilion, long upper lip, submucous cleft palate, antimongoloid slant of palpebral fissures, telecanthus, prominent eyes, short neck with anterior and lateral webbing, short sternum, overlapping toes, wrist contractures, and hypertonicity. Later she was noted to have psychomotor retardation. Eleven previously published cases and our patient suggest that duplication of 6q (involving at least 6q25 leads to 6qter) produces a highly characteristic syndrome.
