NLRP6 and COVID-19: Future studies should explore multiple tag SNPs along thegene-dense genomic region that hosts the three IFITM genes (Ensembl | IFITM genes region, 2020),besides the NLRP6 (NLR family pyrin domain containing 6) genethat encodes the sensor component of the NLRP6 inflammasome and is involved ininnate immunity and inflammation, and IRF7, already shown to beimplicated in severe COVID-19 (see above).
