Collection Method: clinical testing

The c.442T>A (p.Y148N) alteration is located in exon 4 (coding exon 3) of the PDCD1LG2 gene. This alteration results from a T to A substitution at nucleotide position 442, causing the tyrosine (Y) at amino acid position 148 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
