Ambry Genetics

Aug 22, 2023

The c.64G>A (p.V22I) alteration is located in exon 1 (coding exon 1) of the BPI gene. This alteration results from a G to A substitution at nucleotide position 64, causing the valine (V) at amino acid position 22 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
