Back in business! No more M-CRAP :D
What I plan to do in the near future
We've established that there is a demand to classify rs#'s based on clinical importance - one way to go about doing this relatively painlessly is to determine how many people are diagnosed with the disorder when given a disease name. With that in mind, I found a excel file from California which has disease names linked to the CDC naming convention, along with number diagnosed; if I can mine this file given a disease ID, or better yet just an rs#, then we have a basis by which to judge clinical importance.
Note: I'm really sorry guys, but I won't be able to work on this until after the 16th - I have the MCAT on the morning of, but afterwards I'll get to it. Hopefully it won't be too complicated though.
Resources for disease frequency
- CDC Database of morbidity: http://www.cdc.gov/nchs/icd9.htm , in text files which can be parsed
- Diagnosis Frequency data from state of California: http://www.oshpd.ca.gov/hqad/PatientLevel/ICD9_Codes/index.htm
- CDC information for causes of death (in pdf) http://www.cdc.gov/nchs/fastats/lcod.htm
4.18.07: Building off the discussion on 4.17.07, completed a module which takes as input OMIM keywords supplied by Resmi and co. and gives as output ICD9 IDs and prevalence information, based on data from the state of California.
To do: Make it more legible, conglomerate statistics, figure out a way to rank prevalence. Extension required: Find a dB which has ICD9 ID's and genetic prevalance - that would be a gold mine. literally.
