Incontinentia Pigmenti: Ocular Genetic Studies

Incontinentia pigmenti (IP) is a rare X-linked dominant genodermatosis that leads to significant ocular findings. This study examines the ocular effects of IP, its genetic basis, and ocular-genetic findings in animal models. Genetically, the primary cause of IP is mutations in the IKBKG gene. This gene encodes NEMO, a regulatory protein essential for the activation of the NF-?B signaling pathway. NEMO deficiency results in increased susceptibility of cells to apoptosis, contributing to the development of ocular and other ectodermal manifestations of IP. Future therapeutic strategies may include modulation of NF-?B pathways, inhibition of inflammatory cytokines, and targeting apoptotic pathways.
