Reduction of TRPM3 (MIM 608961) is described to be associated with chronic fatigue syndrome/Myalgic encephalomyelitis patients [29], and FGF2 (MIM 134920) has been proposed to play a role in intussusceptive angiogenesis during COVID-19 [30]. This evidence concerns the gene FGF2 and myalgic encephalomeyelitis/chronic fatigue syndrome.
