Ambry Genetics

Nov 09, 2021

The c.557T>C (p.I186T) alteration is located in exon 5 (coding exon 5) of the BPI gene. This alteration results from a T to C substitution at nucleotide position 557, causing the isoleucine (I) at amino acid position 186 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
