The c.346T>C (p.W116R) alteration is located in exon 2 (coding exon 2) of the TMPRSS12 gene. This alteration results from a T to C substitution at nucleotide position 346, causing the tryptophan (W) at amino acid position 116 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
