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]

TET2-AS1 (HGNC:41125): (TET2 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.18 is higher than 0.05.
