Ambry Genetics

Aug 11, 2022

The c.1813C>T (p.R605C) alteration is located in exon 3 (coding exon 2) of the LRFN2 gene. This alteration results from a C to T substitution at nucleotide position 1813, causing the arginine (R) at amino acid position 605 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
