Human SOX14 is localised to a 1.15-Mb yeast artificial chromosome on chromosome 3q23, close to loci for BPES (blepharophimosis, ptosis, epicanthus inversus syndrome) and Mobius syndrome.
This location places SOX14 within a chromosome interval associated with two distinct syndromes that affect craniofacial development: Blepharophimosis-ptosis-epicantus inversus syndrome and Möbius syndrome.
