Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.512T>A (p.L171H) alteration is located in exon 1 (coding exon 1) of the KLRG2 gene. This alteration results from a T to A substitution at nucleotide position 512, causing the leucine (L) at amino acid position 171 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
