SLC2A1 and COVID-19: These were SNPs in the genes ABCG2 (the SNP shown to play a role in gout susceptibility, and ADME (absorption, distribution, metabolism, and excretion) of drugs [42]), PMCA4b (the SNP protecting against malaria [43]), SLC2A1 (SNP associated with impaired T cell recovery in antiretroviral-treated HIV patients [38]), RAVER1 (SNP associated with type-2 diabetes and involvement in chronic COVID19 has also been shown [17]), and UGT2A1/2A2 (SNPs associated with loss of taste and smell in COVID-19).
