Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2022The c.540G>A (p.M180I) alteration is located in exon 4 (coding exon 4) of the TOX2 gene. This alteration results from a G to A substitution at nucleotide position 540, causing the methionine (M) at amino acid position 180 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
