The c.417G>C (p.M139I) alteration is located in exon 6 (coding exon 5) of the TTC12 gene. This alteration results from a G to C substitution at nucleotide position 417, causing the methionine (M) at amino acid position 139 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
