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.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

PM2

Variant has high frequency in the NFE (0.0244) population. However there is too low homozygotes in high coverage region: (expected more than 14, got 1).

BP4

Computational evidence support a benign effect (MetaRNN=0.0036872923).

BP6

Variant 11-1250631-C-T is Benign according to our data. Variant chr11-1250631-C-T is described in ClinVar as [Benign]. Clinvar id is 403177.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
