Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2022The c.89C>T (p.T30I) alteration is located in exon 4 (coding exon 1) of the DTX2 gene. This alteration results from a C to T substitution at nucleotide position 89, causing the threonine (T) at amino acid position 30 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
