Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.775A>G (p.K259E) alteration is located in exon 6 (coding exon 5) of the PDCD1LG2 gene. This alteration results from a A to G substitution at nucleotide position 775, causing the lysine (K) at amino acid position 259 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
