Ambry Genetics

May 31, 2023

The c.422G>C (p.G141A) alteration is located in exon 4 (coding exon 4) of the BPI gene. This alteration results from a G to C substitution at nucleotide position 422, causing the glycine (G) at amino acid position 141 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
