Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2022The c.272C>T (p.T91M) alteration is located in exon 2 (coding exon 2) of the TRAK1 gene. This alteration results from a C to T substitution at nucleotide position 272, causing the threonine (T) at amino acid position 91 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
