What is it about?
Irritable Bowel Syndrome (IBS) is a pervasive gastrointestinal disorder that escapes routine diagnosis due to the lack of a definitive testing methodology. Here, a subset of seven human genes is identified as being dysregulated in patients with IBS. Furthermore, given the close association of vitamin D, serotonin metabolism, and IBS in the gut-brain axis, vitamin D was tested for its ability to regulate both serotonergic and non-serotonergic genes found to be dysregulated in IBS. Following testing, it was found that vitamin D caused a reversal of aberrant gene expression in four IBS-candidate genes.

Why is it important?
This proposed panel of seven genes and supporting evidence of the potential therapeutic effects of vitamin D provides information for the further development of more refined diagnostic tools and therapies to treat IBS.
