The c.2191A>G (p.M731V) alteration is located in exon 15 (coding exon 15) of the TMEM245 gene. This alteration results from a A to G substitution at nucleotide position 2191, causing the methionine (M) at amino acid position 731 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
