Genes affected
TET1 (HGNC:29484): (tet methylcytosine dioxygenase 1) DNA methylation is an epigenetic mechanism that is important for controlling gene expression. The protein encoded by this gene is a demethylase that belongs to the TET (ten-eleven translocation) family. Members of the TET protein family play a role in the DNA methylation process and gene activation. [provided by RefSeq, Sep 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2023The c.778G>A (p.V260I) alteration is located in exon 2 (coding exon 1) of the TET1 gene. This alteration results from a G to A substitution at nucleotide position 778, causing the valine (V) at amino acid position 260 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
