PSMA4 and susceptibility to pneumonia measurement: Specifically, decreased predicted expression of two proximal genes on chromosome 16 were associated with pneumonia susceptibility, NPIPB7 in lung (PTWAS = 7.18 × 10−7) and SULT1A1 in spleen (PTWAS = 8.38 × 10−7), whilst upregulated predicted expression of PSMA4 in whole blood on chromosome 14 also survived correction (PTWAS = 9.36 × 10−7).
