Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.1863G>C (p.Q621H) alteration is located in exon 14 (coding exon 13) of the TRAK2 gene. This alteration results from a G to C substitution at nucleotide position 1863, causing the glutamine (Q) at amino acid position 621 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
