Abstract

Trichorhinophalangeal syndrome type1 (TRPS I) is an extremely rare hereditary disease with mainly autosomal dominant inheritance, which is characterized by a triad of hair,craniofacial, and skeletal abnormalities.Very recently, the responsible geneTRPSI gene has been cloned on human chromosome 8q24 and 8q23.3 (OMIM#190350).We describe a female patient with a sporadic case of TRPS I. DNA analysis of the patient revealed a de novo mutation of c.1029dupC of TRPS I Exon4.This mutation is the first to be reported in TRPS Type I.DNA analysis of her parents revealed no mutation of TRPS I gene.
