Genes affected

TET2 (HGNC:25941): (tet methylcytosine dioxygenase 2) The protein encoded by this gene is a methylcytosine dioxygenase that catalyzes the conversion of methylcytosine to 5-hydroxymethylcytosine. The encoded protein is involved in myelopoiesis, and defects in this gene have been associated with several myeloproliferative disorders. Two variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2011]

Collection Method: clinical testing

The TET2 c.3424T>A variant is predicted to result in the amino acid substitution p.Cys1142Ser. This variant was observed in a healthy cohort in a study of variants in cancer-susceptibility genes (Table S1, Bodian et al. 2014. PubMed ID: 24728327). This variant is listed as likely benign in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/135329/). This variant is intronic in an alternative transcript (NM_001127208:c.3409+15T>A). This variant is reported in 0.12% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-106158523-T-A). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
