The narcolepsy gene allows cells in the hypothalamus to receive messages from other cells. As a result of the mutation, the cells cannot communicate properly, and abnormal sleeping patterns develop.
Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.
Bipolar disorder affects men and women equally and usually appears between the ages of 15 and 25. The exact cause is unknown, but it occurs more often in relatives of people with bipolar disorder.
If you are refering to Hypertrichosis, when the body grows abnormally large amounts of hair, then yes. "Werewolf Syndrome" Is genetic and is thought to be caused by a mutation in one of the chromosomes.

Narcolepsy is an autoimmune disorder in which your immune system, at some point, attacked the protein that signals to the brain that REM sleep is no longer needed during the day. As a result, narcoleptics need more frequent REM sleep.
A lack of the protein hypocretin in the hippocampus and lower thalamus is thought to be the location of the main cause of narcolepsy.

This theory suggests that the person's immune system accidentally turns against the specific area of the brain that controls alertness and sleep, injuring or destroying it.

These days, the Manx cat is at home in any domestic setting. If the question means "Where did the Manx cat originate?", it originated on the Isle of Man. They are thought to share a common ancestry with the British Shorthair, and that it was just a genetic mutation that resulted in the tailless variety we now know as the Manx. This genetic mutation resulted in some kittens being born without the extra vertebrae that form the tail of normal cats.
