Ambry Genetics

Jan 23, 2023

The c.680A>G (p.Y227C) alteration is located in exon 2 (coding exon 2) of the LANCL3 gene. This alteration results from a A to G substitution at nucleotide position 680, causing the tyrosine (Y) at amino acid position 227 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
