Ambry Genetics

Sep 29, 2023

The c.293A>G (p.K98R) alteration is located in exon 2 (coding exon 2) of the NEGR1 gene. This alteration results from a A to G substitution at nucleotide position 293, causing the lysine (K) at amino acid position 98 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
