The c.688A>G (p.M230V) alteration is located in exon 5 (coding exon 5) of the EFCAB14 gene. This alteration results from a A to G substitution at nucleotide position 688, causing the methionine (M) at amino acid position 230 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
