Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.1921A>G (p.I641V) alteration is located in exon 14 (coding exon 13) of the TRAK2 gene. This alteration results from a A to G substitution at nucleotide position 1921, causing the isoleucine (I) at amino acid position 641 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
