Genes affected

TIGD6 (HGNC:18332): (tigger transposable element derived 6) 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. [provided by RefSeq, Oct 2009]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.832C>T (p.R278W) alteration is located in exon 2 (coding exon 1) of the TIGD6 gene. This alteration results from a C to T substitution at nucleotide position 832, causing the arginine (R) at amino acid position 278 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
