FH (P07954) variants and mutations

FH (also known as P07954) is a human protein-coding gene encoding a fumarate hydratase, mitochondrial protein. It converts fumarate to malate in the mitochondrial TCA cycle. Biallelic loss causes fumarase deficiency, while heterozygous loss-of-function variants cause hereditary leiomyomatosis and renal cell cancer syndrome through fumarate accumulation and tumor-suppressor loss. This analysis covers 1,513 FH variants and mutations. Of these, 71% have computational variant effect predictions. Disease context includes hereditary leiomyomatosis and renal cell cancer, fumaric aciduria, and Inherited cancer-predisposing syndrome. Example FH variants include M1I, M1K, and M1L.
