The c.467T>G (p.V156G) alteration is located in exon 7 (coding exon 6) of the TMCO5A gene. This alteration results from a T to G substitution at nucleotide position 467, causing the valine (V) at amino acid position 156 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
