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 remodeling and angiogenesis by facilitating cell-matrix interactions. SMOC1 has been associated with ocular and limb development, and mutations in this gene are linked to Waardenburg anophthalmia syndrome and other developmental disorders.
