Partial deletion of distal 17q

Abstract

A newborn female was found to have a deletion of the terminal portion of 17q. Prominent manifestations included microcephaly, apparent hypertelorism, epicanthic folds, a broad nasal bridge with anteverted nostrils, posteriorly angulated ears, micrognathia, widely spaced nipples, arachnodactyly with proximal thumbs, and a coxa vara deformity. The unbalanced translocation was inherited from the mother, who had a reciprocal translocation involving the terminal portions of 2p and 17q. To the best of our knowledge, this is the first report of a liveborn infant with deletion of the distal portion of 17q with the exception of reports of patients with ring chromosome 17.
