The c.937G>A (p.V313M) alteration is located in exon 9 (coding exon 9) of the EFR3B gene. This alteration results from a G to A substitution at nucleotide position 937, causing the valine (V) at amino acid position 313 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
