Further case of microdeletion of 8q24 with phenotype overlapping Langer-Giedion without TRPS1 deletion

Am J Med Genet A. 2008 Jun 15;146A(12):1587-92. doi: 10.1002/ajmg.a.32347.

Abstract

Langer-Giedion syndrome results from a microdeletion at 8q24.1 encompassing the EXT1 and the adjacent TRPS1 gene. We report on a boy with an oligo array-cgh characterized small microdeletion involving EXT1 alone but with some features of Langer-Giedion syndrome suggesting a functional disturbance of TRPS1. This boy, in addition to a mild Langer-Giedion like phenotype, also had some unusual features including prominent toe pads and fat pads on the soles of his feet similar to those described in Pierpont syndrome.
