Ambry Genetics

Feb 12, 2024

The c.256C>T (p.R86W) alteration is located in exon 1 (coding exon 1) of the LRCH3 gene. This alteration results from a C to T substitution at nucleotide position 256, causing the arginine (R) at amino acid position 86 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
