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)

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_001127208.3. Strenght limited to Supporting due to length of the change: 1aa.
