Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.209C>A (p.T70N) alteration is located in exon 1 (coding exon 1) of the DTWD2 gene. This alteration results from a C to A substitution at nucleotide position 209, causing the threonine (T) at amino acid position 70 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
