For the top panel describing variation details such as source and class, see this help page.

Diseases and traits that are associated with the variation of interest are shown on this page. The sources of these associations are listed in the second column and include:

The reported gene comes directly from the specific study, as does the most associated allele and P value.

It is possible to retrieve the list of variations associated to phenotypes in BioMart whenever this list is greater than 250. Otherwise it can be seen on the Karyotype view.
