Klippel‐Trenaunay‐Weber syndrome associated with a 5:11 balanced translocation

Abstract
We report on a case of Klippel‐Trenaunay Weber syndrome (KTWS) associated with a reciprocal translocation [46,XX,t(5;11)(q13.3;p15.1)]. The patient had developmental delay and minor anomalies in addition to classic findings of KTWS. These data support the notion that Klippel‐Trenaunay‐Weber syndrome may be due to a single gene defect and suggests the possible localization of a Klippel‐Trenaunay‐Weber gene(s) to 5q or 11p.
