Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) has also been defected in some COVID-19 patients.364–366 Clinical studies have shown that TRPM3 channel activity is impaired in patients with post-COVID-19 conditions, which suggests impaired ion mobilization; such condition may impede cellular function and lead to chronic post-infection symptoms such as ME/CFS.367. The gene discussed is TRPM3; the disease is myalgic encephalomeyelitis/chronic fatigue syndrome.
