Ambry Genetics

Feb 22, 2023

The c.2128C>A (p.Q710K) alteration is located in exon 5 (coding exon 4) of the LRRN4 gene. This alteration results from a C to A substitution at nucleotide position 2128, causing the glutamine (Q) at amino acid position 710 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
