The c.1127G>A (p.G376D) alteration is located in exon 4 (coding exon 4) of the CDCP2 gene. This alteration results from a G to A substitution at nucleotide position 1127, causing the glycine (G) at amino acid position 376 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
