SMOC2
Chr 6ARSPARC related modular calcium binding 2
Also known as: DTDP1, DTDP1A, MST117, MSTP117, MSTP140, SMAP2, bA270C4A.1, bA37D8.1
The protein is a matricellular protein that promotes matrix assembly and cell adhesiveness, and stimulates endothelial cell proliferation, migration, and angiogenesis. Biallelic mutations cause dentin dysplasia type IA, an autosomal recessive condition affecting tooth development. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.622), suggesting some tolerance to such mutations.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
Predictions shown for reference only — model trained on dominant genes, not applicable to AR conditions.
The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
