Interstitial 6q deletion with a Prader-Willi-like phenotype: a new case and review of the literature

Eur J Paediatr Neurol. 2000;4(1):39-43. doi: 10.1053/ejpn.1999.0259.

Abstract

We report on an additional fourth case of Prader-Willi (PW)-like phenotype and an interstitial deletion of 6q. Despite sharing clinical characteristics, patients with a PW-like phenotype and a deletion of 6q, have features which distinguish them from Prader-Willi syndrome (PWS) patients. This case emphasizes the need to examine patients with suspected PWS, but who are negative for recognizable deletions of 15q11-q13 or uniparental maternal disomy of chromosome 15, for a deletion of 6q.
