The c.2795G>A (p.G932D) alteration is located in exon 17 (coding exon 17) of the CAPRIN2 gene. This alteration results from a G to A substitution at nucleotide position 2795, causing the glycine (G) at amino acid position 932 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
