Contributing data for scientific research

Got my genome sequenced by the folks at 23andMe, and consented to having my data used in research studies. As a result, some new genetic sites have been identified through the sifting of the aggregate data of other folks like or unlike me.

We humans are pattern identifying organisms. So if you have Parkinson’s but not one of the gene mutations/variations known to “cause” the disease, it is only natural that we would look for correlations and associations that might also result in Parkinsonism.  So scientists mine the DNA data of thousands of people with Parkinson’s and find some additional markers

DNA and Parkinson’s – discovery by association

Not having been trained in the field, I think in broader terms – for instance, if 50% of depression diagnoses eventually become PD cases, and 25% of essential tremor cases result in Parkinson’s cases, doesn’t it stand to reason that a person with depression and essential tremors will have a greater than 50% chance of developing Parkinson’s, assuming their lifetime is long enough?  Or would it be greater than 75%? It would be interesting to see a Venn diagram of overlapping diagnoses…
