Other syndromic cataracts mapping to Xp include chondrodysplasia punctata 2 (Xp11.23-p11.22; OMIM 302960), which is caused by EBP gene mutations [9]; cataracts, ataxia, short stature, and mental retardation (CASM; Xpter-q13.1; OMIM 300619) [10]; Norrie Disease (Xp11.3, OMIM 310600), which is caused by mutations in the NDP gene [11]; and Nance-Horan syndrome (Xp22.13, OMIM 302350), which is caused by mutations in the NHS gene [12]. Here, NHS is linked to cataract.
