The c.3145A>G (p.S1049G) alteration is located in exon 22 (coding exon 22) of the TMC3 gene. This alteration results from a A to G substitution at nucleotide position 3145, causing the serine (S) at amino acid position 1049 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
