The c.1080G>A (p.M360I) alteration is located in exon 6 (coding exon 4) of the TMC5 gene. This alteration results from a G to A substitution at nucleotide position 1080, causing the methionine (M) at amino acid position 360 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
