NOTCH1 (P46531) variants and mutations

NOTCH1 (also known as P46531) is a human protein-coding gene encoding a neurogenic locus notch homolog protein 1 protein. Ligand-dependent cleavage releases an intracellular domain that directly controls transcriptional programs governing cell fate and differentiation. Pathogenic variants can cause congenital aortic-valve disease and left-sided heart defects, while activating or inactivating somatic changes contribute to several cancers. This analysis covers 10,057 NOTCH1 variants and mutations. Of these, 41% have computational variant effect predictions. Disease context includes Adams-Oliver syndrome, B-cell chronic lymphocytic leukemia, and aortic stenosis. Example NOTCH1 variants include M1L, P2A, and P2S.
