Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.2348A>G (p.H783R) alteration is located in exon 16 (coding exon 15) of the TRAK2 gene. This alteration results from a A to G substitution at nucleotide position 2348, causing the histidine (H) at amino acid position 783 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
