Figure 2.
FOXP3 gene structure showing the regulatory regions, the repressor domain, the zinc-finger domain, the leucine-zipper domain, the LZ-FHK loop, and the forkhead domain. The regulatory regions that are target sites for DNA methylation are indicated by blue and green arrows; and for histone modifications by green arrows. The exon localization of the mutations identified in intrauterine IPEX fetuses or neonates from 11 families is depicted. Annotations refer to coding sequence and protein alteration positions; family ID appears between parenthesis.
