Ambry Genetics

Apr 28, 2023

The c.218A>G (p.N73S) alteration is located in exon 3 (coding exon 3) of the POLR1E gene. This alteration results from a A to G substitution at nucleotide position 218, causing the asparagine (N) at amino acid position 73 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
