The c.3061T>C (p.Y1021H) alteration is located in exon 22 (coding exon 22) of the TMC3 gene. This alteration results from a T to C substitution at nucleotide position 3061, causing the tyrosine (Y) at amino acid position 1021 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
