The c.416T>C (p.I139T) alteration is located in exon 2 (coding exon 1) of the CPQ gene. This alteration results from a T to C substitution at nucleotide position 416, causing the isoleucine (I) at amino acid position 139 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
