Progressive scarring lung disease with significant genetic component. MUC5B promoter variant is associated with common sporadic and familial IPF.
How Genetic Is Idiopathic Pulmonary Fibrosis?
Idiopathic Pulmonary Fibrosis involves complex interactions between multiple genes and environmental factors. Heritability estimates range up to 55%, though no single gene determines outcome on its own.
Key genes associated with Idiopathic Pulmonary Fibrosis: TERT TERC MUC5B. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Idiopathic Pulmonary Fibrosis?
Family history can be informative for Idiopathic Pulmonary Fibrosis, but its predictive power is limited because many genes — each with small effects — combine with environmental influences. A family history of the condition may prompt earlier or more frequent screening.
Frequently Asked Questions
Is Idiopathic Pulmonary Fibrosis genetic?
Multiple genes and environmental factors interact to influence risk. Studies suggest heritability of approximately 55%. Key genes involved include TERT TERC MUC5B.
Can a DNA test reveal my risk of Idiopathic Pulmonary Fibrosis?
Genetic testing can identify relevant variants, though Idiopathic Pulmonary Fibrosis risk is influenced by many factors. Talk to your doctor about appropriate testing.
Does family history matter for Idiopathic Pulmonary Fibrosis?
Family history can be informative for Idiopathic Pulmonary Fibrosis, but its predictive power is limited because many genes with small individual effects combine with environmental influences.
Is Idiopathic Pulmonary Fibrosis hereditary, meaning it's passed directly from parent to child?
Idiopathic Pulmonary Fibrosis follows a polygenic inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
