The c.152T>C (p.I51T) alteration is located in exon 3 (coding exon 2) of the CNPY2 gene. This alteration results from a T to C substitution at nucleotide position 152, causing the isoleucine (I) at amino acid position 51 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
