The c.392T>C (p.I131T) alteration is located in exon 5 (coding exon 5) of the TIMM17A gene. This alteration results from a T to C substitution at nucleotide position 392, causing the isoleucine (I) at amino acid position 131 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
