Calculating odds ratio for single variable

Question

[biobudhan]

I am trying to understand what are the odds of a SNP being in intergenic, intronic, exonic, UTr3 or UTR5 regions. My data looks similar to this:

ID  chrom        pos      ref   alt homozygosity      heterozygosity      sampleMaf refSeq.siteType homo_ref        het  homo_alt       total.samples

snp4    chr4    98918764    C   T   0.138                0.435               0.355        exonic         115    117 37  269

I have the above information and I am not sure how to proceed.
