Ambry Genetics

Mar 14, 2023

The c.23G>A (p.R8H) alteration is located in exon 2 (coding exon 1) of the EPN3 gene. This alteration results from a G to A substitution at nucleotide position 23, causing the arginine (R) at amino acid position 8 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
