NOTCH3 (Q9UM47) variants and mutations

NOTCH3 (also known as Q9UM47) is a human protein-coding gene encoding a neurogenic locus notch homolog protein 3 protein. Its signaling helps maintain vascular smooth-muscle and mural-cell identity in small arteries. Pathogenic cysteine-altering variants cause CADASIL, with migraine, recurrent ischemic strokes, white-matter disease, and progressive cognitive impairment. This analysis covers 5,573 NOTCH3 variants and mutations. Of these, 79% have computational variant effect predictions. Disease context includes cerebral arteriopathy, autosomal dominant, with subcortical infarcts and leukoen, CADASIL, and lateral meningocele syndrome. Example NOTCH3 variants include M1K, P3L, and G4R.
