With the emergence of the COVID-19 pandemic, host genetic loci affecting the infection and severity of the disease were only reported in Asian populations such as TMEM189-UBE2V1 locus and HLA alleles in Chinese patients [32], rs60200309-A at DOCK2 in Japanese patients [42], and 5q32 and 12q22 in Thai patients [11]. This evidence concerns the gene DOCK2 and infection.
