COVID-19

"DNMT3A and TET2 mutations were by far the most common, concerning 28 (23%) and 26 patients (21%), respectively. Overall, mutations in DNMT3A and/or TET2 were present in 36% (44/122) of COVID-19 patients and were found in 80% (44/55) of those with CH. Ten patients had both DNMT3A and TET2 mutations."

Gq/11

"At a molecular level, progression of CH to MPD is accompanied by selection for mutations activating Ras/Raf/MAPK signaling."

Thyroid

"In the mouse and other mammals, DNMT3A is a TH-induced gene, implicated not only in brain development but also in that of other tissues, including those involved in metabolic control, such as the hypothalamus and the liver."

"In addition, individuals with TT and CT genotypes and hypothyroidism showed elevated amount of DNMT3a in nuclear extracts of PBMC compared with controls, while no significant difference in DNMT1 levels was observed."
