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 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.
FAQs
Is narcolepsy genetic?
Yes, certain genetic markers like DQB1*0602 increase risk.
What triggers narcolepsy?
Infections like streptococcus and influenza can trigger it.
Can it run in families?
Yes, though it's rare and complex.
Wrapping Up
Understanding genetic and environmental factors is key to managing narcolepsy risk.
