POT1 (Q9NUX5) variants and mutations

POT1 (also known as Q9NUX5) is a human protein-coding gene encoding a protection of telomeres protein 1 protein. It binds the single-stranded ends of telomeres and helps control telomerase access while preventing chromosome ends from being mistaken for DNA breaks. Germline loss-of-function variants predispose to several cancers, including melanoma, glioma, and chronic lymphocytic leukemia, and can produce unusually long telomeres. This analysis covers 1,567 POT1 variants and mutations. Of these, 67% have computational variant effect predictions. Disease context includes tumor predisposition syndrome 3, B-cell chronic lymphocytic leukemia, and familial melanoma. Example POT1 variants include M1?, M1I, and M1T.
