Your genes may significantly impact your risk of developing narcolepsy. Discover how genetic factors and environmental triggers can influence this condition.

Genetic Risk Factors

The DQB1*0602 haplotype is a significant genetic risk factor for Type 1 narcolepsy, present in most affected individuals. Other human leukocyte antigen (HLA) haplotypes can also impact risk. Understanding your genetic predisposition can provide insight into your narcolepsy risk.

Environmental Triggers

While genetics play a role, environmental factors like infections can trigger narcolepsy. Streptococcus and influenza are known triggers. These factors are crucial in understanding and managing narcolepsy risk.

Narcolepsy is a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. Genetic factors such as the DQB1*0602 haplotype and environmental triggers like infections may increase the risk.

Narcolepsy in Families

Narcolepsy sometimes runs in families, though this is rare. Family members may experience isolated symptoms or even narcolepsy without genetic markers. This suggests a complex interplay of genetic and environmental factors.

Frequently Asked Questions

Yes, certain genetic markers like DQB1*0602 increase risk.

Infections like streptococcus and influenza can trigger it.

Yes, though it's rare and complex.

Key Takeaways

Understanding genetic and environmental factors is key to managing narcolepsy risk.
