The c.188T>C (p.M63T) alteration is located in exon 1 (coding exon 1) of the KCTD12 gene. This alteration results from a T to C substitution at nucleotide position 188, causing the methionine (M) at amino acid position 63 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
