Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.994A>G (p.I332V) alteration is located in exon 7 (coding exon 7) of the TOX4 gene. This alteration results from a A to G substitution at nucleotide position 994, causing the isoleucine (I) at amino acid position 332 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
