Genes affected

TRPM2 (HGNC:12339): (transient receptor potential cation channel subfamily M member 2) The protein encoded by this gene forms a tetrameric cation channel that is permeable to calcium, sodium, and potassium and is regulated by free intracellular ADP-ribose. The encoded protein is activated by oxidative stress and confers susceptibility to cell death. Alternative splicing results in multiple transcript variants encoding distinct protein isoforms. Additional transcript variants of this gene have been described, but their full-length nature is not known. [provided by RefSeq, Feb 2016]

Ambry Genetics

Nov 30, 2022

The c.701G>T (p.G234V) alteration is located in exon 5 (coding exon 5) of the TRPM2 gene. This alteration results from a G to T substitution at nucleotide position 701, causing the glycine (G) at amino acid position 234 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
