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 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.005108267).
• BP6: Variant 4-105236541-T-C is Benign according to our data. Variant chr4-105236541-T-C is described in ClinVar as [Benign]. Clinvar id is 135323.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00664 (1012/152296) while in subpopulation NFE AF= 0.011 (749/68018). AF 95% confidence interval is 0.0104. There are 5 homozygotes in gnomad4. There are 444 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 5 AR gene
