Most cases of narcolepsy have no other family members affected with narcolepsy and the risk is very small. If you have narcolepsy-cataplexy, the risk for your child to develop narcolepsy-cataplexy is only 1-2%. The risk of developing daytime sleepiness without cataplexy may be slightly higher (4%). These risks are probably smaller if you carry the HLA-DQB1*0602 subtype and have no other family member with narcolepsy.
