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.569C>T (p.A190V) alteration is located in exon 4 (coding exon 4) of the TRPC1 gene. This alteration results from a C to T substitution at nucleotide position 569, causing the alanine (A) at amino acid position 190 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
