Earlier research had claimed that people who had melanoma running in their families were at a higher risk of getting Parkinson's. However, a new research now claims that there is no connection between these two diseases. The researchers of the new study though are quick to point out that this does not mean that there is no genetic connection between Parkinson's and melanoma. There could be, but this connection may not have an effect.
Melanoma is a kind of skin cancer that is no very common, but it can be quite aggressive and fatal. It has been seen that this kind of cancer is prevalent in families and if a person has a couple of close relatives who have been diagnosed with melanoma, then he or she is at a higher risk of getting it.
A study conducted in 2009 on over 150,000 adults concluded that melanoma patients' parents, siblings and kids were twice as likely to get Parkinson's compared to people who did not melanoma running in their immediate family. In another research, the researchers found that a gene named MC1R, which is responsible for red hair and higher risk of melanoma, was also the gene that increased a person's risk to Parkinson's.
These two studies' findings were similar to studies conducted in the UK, the US and Denmark a few years ago which concluded that people suffering from Parkinson's had a higher chance of contracting melanoma.
While all these studies imply that the same gene is responsible for causing Parkinson's and melanoma, they have not been able to prove this fact.
