Genes affected

MUC5B (HGNC:7516): (mucin 5B, oligomeric mucus/gel-forming) This gene encodes a member of the mucin family of proteins, which are highly glycosylated macromolecular components of mucus secretions. This family member is the major gel-forming mucin in mucus. It is a major contributor to the lubricating and viscoelastic properties of whole saliva, normal lung mucus and cervical mucus. This gene has been found to be up-regulated in some human diseases, including sinus mucosa of chronic rhinosinusitis (CRS), CRS with nasal polyposis, chronic obstructive pulmonary disease (COPD) and H. pylori-associated gastric disease, and it may be involved in the pathogenesis of these diseases.

Ile4979Ile in exon 32 of MUC5B: This variant is not expected to have clinical si gnificance because it does not alter an amino acid residue and is not located wi thin the splice consensus sequence. It has been identified in 3.2% (273/8438) of European American chromosomes from a broad population by the NHLBI Exome Sequen cing Project (http://evs.gs.washington.edu/EVS; dbSNP rs148759448). -
