TRPC6 gene

The TRPC6 gene encodes an cation channel which is involved in podocyte function. When mutated, familial FSGS 2 or pulmonary arterial hypertension may ensue. It is not clear at the moment whether solely gain-of-function mutations can cause the disease of loss-of-funtion mutations too.

Gene Structure

The gene TRPC6 is located on chromosome 11 (11q21-q22). It consists of 13 exons, all coding, that stetch about 134.3kb.
