We found that four polymorphisms in FCGR2B, IFI16, and STING1 were associated with the GW score, an index of MPS, and that a polymorphism in LRRFIP1 was associated with both the GW and SPES scores, the latter an index of porcine pleuropneumonia. The gene discussed is LRRFIP1; the disease is mucopolysaccharidosis.
