Jul 30, 2024

The c.526G>A (p.V176M) alteration is located in exon 4 (coding exon 4) of the TMC7 gene. This alteration results from a G to A substitution at nucleotide position 526, causing the valine (V) at amino acid position 176 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
