Ambry Genetics

Oct 12, 2021

The c.94G>T (p.A32S) alteration is located in exon 1 (coding exon 1) of the BPIFB3 gene. This alteration results from a G to T substitution at nucleotide position 94, causing the alanine (A) at amino acid position 32 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
