Narcolepsie : est-ce héréditaire ? La composante génétique expliquée clairement, vérifiée avec des sources médicales.
Original
Narcolepsy has genetic components such as the HLA (human leucocitary antigen) complex in the cromossoma 6 allele.
So it means somehow your genes can manifestate the disease or not. It doesnt mean that some one in the family has the manisfestation of the disease.
