Notably, research from the Getx study found that rs73009538 serves as an eQTL for SMARCA4, a key component of the SWI/SNF complex that regulates immune responses and gene expression (Rhoads et al., 2018), particularly ACE2, the primary receptor for COVID-19 (Zoufaly et al., 2020). The gene discussed is SMARCA4; the disease is COVID-19.
