Ambry Genetics

Mar 27, 2023

The c.524A>G (p.K175R) alteration is located in exon 1 (coding exon 1) of the LRRC18 gene. This alteration results from a A to G substitution at nucleotide position 524, causing the lysine (K) at amino acid position 175 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
