Methods and compositions for risk prediction, diagnosis, prognosis, and treatment of pulmonary disorders
The invention provides diagnostic and therapeutic targets for pulmonary disease, in particular, fibrotic lung disease. The inventors have found that a genetic variant MUC5B gene is associated with increased expression of the gene, increased risk of developing a pulmonary disease, and an improved prognosis and survival among those developing the pulmonary disease.
1. A method of detecting a genetic variant MUC5B gene in a human subject with a pulmonary fibrotic condition, wherein said genetic variant MUC5B gene is a T allele at the rs35705950 single nucleotide polymorphism (SNP), the method comprising:
assaying a biological sample from the human subject with a pulmonary fibrotic condition, and
detecting a T allele at the rs35705950 SNP in the human subject with a pulmonary fibrotic condition.
2. A method of detecting a genetic variant MUC5B gene in a human subject with idiopathic pulmonary fibrosis (IPF) or familial interstitial pneumonia (FIP), wherein said genetic variant MUC5B gene is a T allele at the rs35705950 single nucleotide polymorphism (SNP), the method comprising:
assaying a biological sample from the human subject with IPF or FIP, and
detecting a T allele at the rs35705950 SNP in the human subject with IPF or FIP.
3. A method of detecting a genetic variant MUC5B gene in a human subject with a family history of idiopathic pulmonary fibrosis (IPF) or familial interstitial pneumonia (FIP), wherein said genetic variant MUC5B gene is a T allele at the rs35705950 single nucleotide polymorphism (SNP), the method comprising:
assaying a biological sample from the human subject with a family history of IPF or FIP, and
detecting a T allele at the rs35705950 SNP in the human subject with a family history of IPF or FIP.
