Similarly, another study conducted in the UK, showed that 7.3% of 247 patients had persisting lymphopaenia; 30.1% of 229 had elevated D-dimer and 9.5% of 190 patients had elevated C reactive protein (CRP), in addition to other persisting symptoms such as difficulty in breathing, cough and fatigue depression and sleep disorders (Table 2) [12]. The gene discussed is CRP; the disease is sleep disorder.
