The TRPS1 gene encodes a multi zinc-finger nuclear regulator of chondrocyte proliferation and differentiation []. Mutations in the gene cause trichorhinophalangeal syndrome (TRPS), an autosomal dominant skeletal dysplasia []. The Trps1 protein also acts as regulator of histone deacetylation, interacting with two histone deacetylases, Hdac1 and Hdac4, thereby increasing their activity [].
