Hemophagocytic lymphohistiocytosis in a female patient due to a heterozygous XIAP mutation and skewed X chromosome inactivation

Abstract excerpt

Genetic forms of hemophagocytic lymphohistiocytosis (HLH) are caused by mutations in autosomal recessive genes affecting perforin-dependent cytotoxic function and two X-linked genes affecting distinct cell signaling pathways: SH2D1A and XIAP. HLH caused by mutations in X-linked genes is typically found only in males. Here we report the occurrence of HLH in a female caused by a heterozygous mutation in XIAP. Flow...
