Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2024The c.323G>A (p.R108Q) alteration is located in exon 5 (coding exon 2) of the DTX2 gene. This alteration results from a G to A substitution at nucleotide position 323, causing the arginine (R) at amino acid position 108 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
