A 5-year-old girl with interstitial deletion of 3p14: Clinical, psychologic, cytogenetic, and molecular studies

Abstract

An interstitial deletion of segment 3p14 (breakpoints 3p21.1 and 3p13) was found in a 5-year-old short, microcephalic, and mentally retarded girl with a pattern of anomalies comprising a wide forehead, short up-slanting palpebral fissures, small nose and ears, hypoplasia of larynx, trachea, and bronchi, clino- and camptodactyly of little fingers, and sacral vertebral fusion. Determination of microsatellites mapping to the deleted segment demonstrated that the deletion had occurred in the paternal germ line. This is the seventh patient with a deletion of 3p14, and comparison with the six previously reported cases does not yet allow definition of a specific pattern of minor and major anomalies.
