Ambry Genetics

Oct 27, 2022

The c.197A>G (p.N66S) alteration is located in exon 5 (coding exon 5) of the MEP1A gene. This alteration results from a A to G substitution at nucleotide position 197, causing the asparagine (N) at amino acid position 66 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
