*These are the known disease genes, associated with other disease subtypes, which have physical protein–protein interactions with the candidate disease genes.

†Square brackets contain OMIM numbers for both diseases and genes.

A prediction is considered confirmed if it is known in published reports to be causative for the relevant disease, and considered refuted if a different gene in the same locus is known to be causative for that disease. It is important to note that a “refuted” candidate gene may not have been screened and excluded, and may thus still be a valid candidate.
