Ambry Genetics

Jul 26, 2022

The c.68G>A (p.R23H) alteration is located in exon 3 (coding exon 1) of the NRSN1 gene. This alteration results from a G to A substitution at nucleotide position 68, causing the arginine (R) at amino acid position 23 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
