Genes affected

TRPC1 (HGNC:12333): (transient receptor potential cation channel subfamily C member 1) The protein encoded by this gene is a membrane protein that can form a non-selective channel permeable to calcium and other cations. The encoded protein appears to be induced to form channels by a receptor tyrosine kinase-activated phosphatidylinositol second messenger system and also by depletion of intracellular calcium stores. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.64T>C (p.S22P) alteration is located in exon 1 (coding exon 1) of the TRPC1 gene. This alteration results from a T to C substitution at nucleotide position 64, causing the serine (S) at amino acid position 22 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
