Ambry Genetics

Sep 26, 2023

The c.20G>A (p.R7Q) 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 20, causing the arginine (R) at amino acid position 7 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
