The c.940A>G (p.M314V) alteration is located in exon 10 (coding exon 10) of the TM6SF2 gene. This alteration results from a A to G substitution at nucleotide position 940, causing the methionine (M) at amino acid position 314 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
