Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.826G>A (p.V276M) alteration is located in exon 5 (coding exon 5) of the TOX2 gene. This alteration results from a G to A substitution at nucleotide position 826, causing the valine (V) at amino acid position 276 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
