MUC5B c.-3133G>T has been associated with increased risk for idiopathic pulmonary fibrosis. This variant has been observed in multiple ethnic backgrounds with highest frequencies in individuals of Ashkenazi Jewish ancestry (16.2%, Genome Aggregation Database (gnomAD); rs35705950) and is present in ClinVar (ID: 30126). Several studies have reported an odds ratios between 3.7-8.3 for developing pulmonary fibrosis in heterozygous individuals (OR=6.3 [95% CI 4.6-8.7] Borie 2013, OR=6.3 [95% CI 3.1-12.7] Hunninghake 2013, OR=8.3 [95% CI 5.8-11.9] Seibold 2013, OR=4.9 [95% CI 3.42-7.03] Stock 2013, OR=5.72 [95% CI 4.7-7.1] Lee 2015, OR=6.2 [95% CI 5.14-7.48] Zhu 2015) and odds ratios between 11.3-21.7 for developing pulmonary fibrosis in homozygous individuals (OR=21.7 [95% CI 104-45.3] Borie 2013, OR=12.98 [95% CI 7.97-21.12] Lee 2015, OR=11.29 [95% CI 5.69-22.40] Zhu 2015). MUC5B c.-3133G>T is a promoter variant that results in increased MUC5B expression (Seibold 2011, Nakano 2016, Kaur 2017). In summary, this variant is an established risk factor for idiopathic pulmonary fibrosis. -
