But thanks to some researchers in Japan, it has been discovered that Narcolepsy and genes known as singe nucleotide polymorphisms or SNP. SNP is a DNA sequence variation between members of a species.
During the research, researchers discovered a genetically mutated fragment of chromosome 22 which increased subjects’ vulnerability to the disease by 1.8 times. Researchers also discovered that the mutation causes a malfunction of the gene CPT1B, which is linked to sleep. Researchers also found that a link between the genetic mutation and narcolepsy was also found in South Koreans.
