Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.937G>T (p.A313S) alteration is located in exon 3 (coding exon 3) of the KLRG2 gene. This alteration results from a G to T substitution at nucleotide position 937, causing the alanine (A) at amino acid position 313 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
