A SNP altering the MUC5AC mucin structure is increased in idiopathic pulmonary fibrosis together with the MUC5B SNP.
A genetic variant linked to mucus buildup appears more common in lung fibrosis patients, suggesting a new avenue for understanding disease origin.
MUC5AC SNP rs878913005 (Arg1201Trp; stabilizes secreted mucin nets) has 1.49x increased frequency in IPF patients vs. controls (OR 2.09, P<0.0001) and is in linkage disequilibrium with the MUC5B promoter SNP; both mucins accumulate in IPF honeycomb cysts.
What the study was
- Study design
- Genetic case-control study (UK Biobank) with tissue immunohistochemistry
- Category
- sentinel
- Maturity
- Validated
Why it surfaced
Novel genetic finding in IPF, a fatal rare lung disease with high unmet need; expands the mucin-genetics IPF model beyond MUC5B; UK Biobank scale provides statistical power. Sentinel capture relevant for rare disease and genetic biomarker topics.
