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.

The p.Lys690Glu variant in MUC5B has not been previously reported in individuals with pulmonary disease, but has been identified in 0.2% (9/3796) of African chr omosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.o rg; dbSNP rs376986344). Computational prediction tools and conservation analysis suggest that the p.Lys690Glu variant may impact the protein, though this inform ation is not predictive enough to determine pathogenicity. In summary, the clini cal significance of the p.Lys690Glu variant is uncertain. -
