Class labels for gene-disease interaction data

Question

[alireza.mdi]

I have two questions and will appreciate your help:

1. I have a gene-disease interaction dataset. For the genes, their names as well as their Entrez ID are available. For the disease, their UMLS ID as well as their names are available. Is their any website or software that accepts disease and gene lists as input and output their disease class such as : cancer, developmental, Renal, etc? Alternatively do you know any gene-disease interaction dataset with interaction scores as well as class labels for both the genes and diseases?
2. How to convert UMLS disease IDs to their OMIM IDs?
