The c.2641A>T (p.R881W) alteration is located in exon 22 (coding exon 22) of the TMC3 gene. This alteration results from a A to T substitution at nucleotide position 2641, causing the arginine (R) at amino acid position 881 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
