Ambry Genetics

Nov 12, 2021

The c.1689G>T (p.K563N) alteration is located in exon 7 (coding exon 6) of the LRRIQ3 gene. This alteration results from a G to T substitution at nucleotide position 1689, causing the lysine (K) at amino acid position 563 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
