The c.167T>C (p.M56T) alteration is located in exon 3 (coding exon 2) of the CCP110 gene. This alteration results from a T to C substitution at nucleotide position 167, causing the methionine (M) at amino acid position 56 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
