The c.844A>C (p.I282L) alteration is located in exon 8 (coding exon 8) of the BPIFC gene. This alteration results from a A to C substitution at nucleotide position 844, causing the isoleucine (I) at amino acid position 282 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
