The c.1888C>T (p.R630W) alteration is located in exon 12 (coding exon 12) of the CPXM2 gene. This alteration results from a C to T substitution at nucleotide position 1888, causing the arginine (R) at amino acid position 630 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
