Genes affected
TIGD2 (HGNC:18333): (tigger transposable element derived 2) The protein encoded by this gene belongs to the tigger subfamily of the pogo superfamily of DNA-mediated transposons in humans. These proteins are related to DNA transposons found in fungi and nematodes, and more distantly to the Tc1 and mariner transposases. They are also very similar to the major mammalian centromere protein B. The exact function of this gene is not known. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 13, 2022The c.1199T>C (p.I400T) alteration is located in exon 1 (coding exon 1) of the TIGD2 gene. This alteration results from a T to C substitution at nucleotide position 1199, causing the isoleucine (I) at amino acid position 400 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
