The c.940G>A (p.D314N) alteration is located in exon 4 (coding exon 2) of the CALHM2 gene. This alteration results from a G to A substitution at nucleotide position 940, causing the aspartic acid (D) at amino acid position 314 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
