Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.2315C>T (p.A772V) alteration is located in exon 16 (coding exon 15) of the TRAK2 gene. This alteration results from a C to T substitution at nucleotide position 2315, causing the alanine (A) at amino acid position 772 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
