The c.367A>G (p.M123V) alteration is located in exon 3 (coding exon 3) of the TEX40 gene. This alteration results from a A to G substitution at nucleotide position 367, causing the methionine (M) at amino acid position 123 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
