Ambry Genetics

Oct 07, 2024

The c.1388T>C (p.I463T) alteration is located in exon 14 (coding exon 14) of the BPIFC gene. This alteration results from a T to C substitution at nucleotide position 1388, causing the isoleucine (I) at amino acid position 463 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
