Ambry Genetics

Dec 17, 2023

The c.62T>G (p.V21G) alteration is located in exon 1 (coding exon 1) of the LRRC52 gene. This alteration results from a T to G substitution at nucleotide position 62, causing the valine (V) at amino acid position 21 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
