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.1433G>A (p.R478H) alteration is located in exon 8 (coding exon 8) of the TRPC1 gene. This alteration results from a G to A substitution at nucleotide position 1433, causing the arginine (R) at amino acid position 478 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
