Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 05, 2024The c.2660A>G (p.N887S) 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 2660, causing the asparagine (N) at amino acid position 887 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
