The c.1478G>A (p.G493D) alteration is located in exon 15 (coding exon 15) of the BPIFC gene. This alteration results from a G to A substitution at nucleotide position 1478, causing the glycine (G) at amino acid position 493 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
