SMOC1 (SPARC Related Modular Calcium Binding 1): SMOC1 is a member of the SPARC family of matricellular proteins. It plays a key role in tissue remodelling and angiogenesis, being crucial for cell-matrix interactions. SMOC1 is linked to ocular and limb development, with mutations in this gene associated with Waardenburg anophthalmia syndrome and other developmental disorders.
