Ambry Genetics

Apr 18, 2023

The c.212T>C (p.I71T) alteration is located in exon 2 (coding exon 2) of the ENO4 gene. This alteration results from a T to C substitution at nucleotide position 212, causing the isoleucine (I) at amino acid position 71 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
