Cl. Bennett et al., The immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome (IPEX) is caused by mutations of FOXP3, NAT GENET, 27(1), 2001, pp. 20-21
IPEX is a fatal disorder characterized by immune dysregulation, polyendocri
nopathy, enteropathy and X-linked inheritance (MIM 304930). We present gene
tic evidence that different mutations of the human gene FOXP3, the ortholog
of the gene mutated in scurfy mice (Foxp3), causes IPEX syndrome. Recent l
inkage analysis studies mapped the gene mutated in IPEX to an interval of 1
7-20-cM at Xp11.23-Xq13.3 (refs. 1,2).
