Ambry Genetics

Nov 21, 2023

The c.620G>A (p.C207Y) alteration is located in exon 1 (coding exon 1) of the LRRC26 gene. This alteration results from a G to A substitution at nucleotide position 620, causing the cysteine (C) at amino acid position 207 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
