The c.516C>G (p.F172L) alteration is located in exon 3 (coding exon 1) of the CALHM2 gene. This alteration results from a C to G substitution at nucleotide position 516, causing the phenylalanine (F) at amino acid position 172 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
