Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.425G>A (p.R142H) alteration is located in exon 3 (coding exon 3) of the THEMIS2 gene. This alteration results from a G to A substitution at nucleotide position 425, causing the arginine (R) at amino acid position 142 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
