1. A method for treating inflammatory bowel disease (IBD) comprising detecting the presence of at least one IBD-associated single nucleotide polymorphism (SNP) in a target polynucleotide comprising:

(a) isolating nucleic acids from a biological sample from a subject;

(b) detecting in the nucleic acids the presence of at least one IBD-associated-SNP selected from a Tat rs2315008 in the TNFRSF6B gene, an A at rs4809330 on chromosome 20 in the TNFRSF6B gene, and an A at rs2836878 on chromosome 21; and diagnosing the subject as having IBD or an increased risk of IBD based on the presence of the detected IBD-associated-SNP; and

(c) administering to the subject a therapeutically effective amount of a therapy useful for treating IBD.

2. The method of claim 1 , further comprising, detecting in the sample the presence of an IBD-associated SNP of an A at rs1968752.

3. The method of claim 1 , wherein the target nucleic acid is amplified prior to detection.

4. The method of claim 1 , wherein the target nucleic acid is DNA.

5. The method of claim 1 , wherein nucleic acids comprising said polymorphism are obtained from an isolated cell of a human subject.

6. The method of claim 2 , wherein the target nucleic acid is amplified prior to detection.
