Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.382G>A (p.G128S) alteration is located in exon 3 (coding exon 3) of the DTWD2 gene. This alteration results from a G to A substitution at nucleotide position 382, causing the glycine (G) at amino acid position 128 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
