TNFRSF1A and pneumonia: FOCUS finemapping of marginal TWAS statistics in and around the genome-wide significant locus on chromosome 12 provided further support to TNFRSF1A as a pneumonia risk gene, with the highest posterior inclusion probability (PIP) in the 90% credible set assigned to a TNFRSF1A GReX model in blood for which increased expression was correlated with pneumonia (PIP = 0.724).
