Ambry Genetics

Apr 26, 2023

The c.142G>A (p.E48K) alteration is located in exon 3 (coding exon 3) of the NSRP1 gene. This alteration results from a G to A substitution at nucleotide position 142, causing the glutamic acid (E) at amino acid position 48 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
