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.

MUC5B-AS1 (HGNC:53936): (MUC5B antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002051562).
• BP6: Variant 11-1242527-A-G is Benign according to our data. Variant chr11-1242527-A-G is described in ClinVar as [Benign]. Clinvar id is 403130.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0251 (3823/152086) while in subpopulation NFE AF= 0.0327 (2221/67964). AF 95% confidence interval is 0.0315. There are 63 homozygotes in gnomad4. There are 1898 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 3823 AD gene.
