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.106G>A (p.D36N) alteration is located in exon 1 (coding exon 1) of the TRPC1 gene. This alteration results from a G to A substitution at nucleotide position 106, causing the aspartic acid (D) at amino acid position 36 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
