Ambry Genetics

May 27, 2022

The c.871A>C (p.I291L) alteration is located in exon 9 (coding exon 9) of the EFR3B gene. This alteration results from a A to C substitution at nucleotide position 871, causing the isoleucine (I) at amino acid position 291 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
