Molecular and structural analysis of two novel STAR mutations in patients with lipoid congenital adrenal hyperplasia.

354 - 357.
Mutations in the gene encoding steroidogenic acute regulatory protein (StAR) cause lipoid congenital adrenal hyperplasia. We report a novel homozygous splice site mutation (IVS1 + 2T --> G) in STAR in two sisters (46XY, 46XX) who presented with primary adrenal insufficiency at birth and a novel homozygous R182H missense mutation in the putative lipid transfer domain of StAR in a phenotypic female (46XY) with adrenal failure and a parotid tumor. These cases highlight the importance of StAR-dependent steroidogenesis during fetal development and early infancy and of the critical functional role of R182 in cholesterol transport.
