Ambry Genetics

Nov 01, 2022

The c.620C>A (p.T207N) alteration is located in exon 6 (coding exon 6) of the NEMP2 gene. This alteration results from a C to A substitution at nucleotide position 620, causing the threonine (T) at amino acid position 207 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
