Ambry Genetics

Feb 22, 2023

The c.351G>T (p.W117C) alteration is located in exon 3 (coding exon 1) of the CALHM2 gene. This alteration results from a G to T substitution at nucleotide position 351, causing the tryptophan (W) at amino acid position 117 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
