The c.89C>T (p.A30V) alteration is located in exon 1 (coding exon 1) of the BPI gene. This alteration results from a C to T substitution at nucleotide position 89, causing the alanine (A) at amino acid position 30 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
