Ambry Genetics

Mar 07, 2024

The c.53C>T (p.A18V) alteration is located in exon 2 (coding exon 1) of the PDCD1LG2 gene. This alteration results from a C to T substitution at nucleotide position 53, causing the alanine (A) at amino acid position 18 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
