An enzymatic deficiency that results in exacerbated bodily response to inflammatory agents.

The most common chronic disease affecting children and young adults. It is a complex genetic disorder with a heterogeneous phenotype, largely attributed to the interactions among many genes and between these genes and the environment. It is characterized by recurrent attacks of paroxysmal dyspnea, with weezing due to spasmodic contraction of the bronchi. Note=PLA2G7 variants can be a risk factor for the development of asthma and PLA2G7 may act as a modifier gene that modulates the severity of this disease.<ref>PMID:10733466</ref>  Defects in PLA2G7 are a cause of susceptibility to atopic hypersensitivity (ATOPY) [MIM:[http://omim.org/entry/147050 147050]]. A condition characterized by predisposition to develop hypersensitivity reactions. Atopic individuals can develop eczema, allergic rhinitis and allergic asthma.<ref>PMID:10733466</ref>

[[http://www.uniprot.org/uniprot/PAFA_HUMAN PAFA_HUMAN]] Modulates the action of platelet-activating factor (PAF) by hydrolyzing the sn-2 ester bond to yield the biologically inactive lyso-PAF. Has a specificity for substrates with a short residue at the sn-2 position. It is inactive against long-chain phospholipids.
