R Dataset / Package gap / aldh2
On this R-data statistics page, you will find information about the aldh2 data set which pertains to ALDH2 markers and Alcoholism. The aldh2 data set is found in the gap R package. You can load the aldh2 data set in R by issuing the following command at the console data("aldh2"). This will load the data into a variable called aldh2. If R says the aldh2 data set is not found, you can try installing the package by issuing this command install.packages("gap") and then attempt to reload the data with the library() command. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the aldh2 R data set. The size of this file is about 10,921 bytes.
ALDH2 markers and Alcoholism
Description
This data set contains eight ALDH2 markers and Japanese alcohlic patients (y=1) and controls (y=0). There are genotypes for 8 loci, with a prefix name (e.g., "EXON12") and a suffix for each of two alleles (".a1" and ".a2").
The eight markers loci follows the following map (base pairs)
| D12S2070 | (> 450 000), |
| D12S839 | (> 450 000), |
| D12S821 | (~ 400 000), |
| D12S1344 | ( 83 853), |
| EXON12 | ( 0), |
| EXON1 | ( 37 335), |
| D12S2263 | ( 38 927), |
| D12S1341 | (> 450 000) |
