Genes affected

TRPC3 (HGNC:12335): (transient receptor potential cation channel subfamily C member 3) 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.2701G>A (p.E901K) alteration is located in exon 12 (coding exon 12) of the TRPC3 gene. This alteration results from a G to A substitution at nucleotide position 2701, causing the glutamic acid (E) at amino acid position 901 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
