Genes affected

PAFAH1B2 (HGNC:8575): (platelet activating factor acetylhydrolase 1b catalytic subunit 2) Platelet-activating factor acetylhydrolase (PAFAH) inactivates platelet-activating factor (PAF) into acetate and LYSO-PAF. This gene encodes the beta subunit of PAFAH, the other subunits are alpha and gamma. Multiple alternatively spliced transcript variants have been described for this gene.
