Ambry Genetics

Oct 26, 2022

The c.991G>T (p.V331L) alteration is located in exon 11 (coding exon 11) of the GLYR1 gene. This alteration results from a G to T substitution at nucleotide position 991, causing the valine (V) at amino acid position 331 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
