Is there any software that analysis co-occuring mutations in the dna? Or any database where I can find this type of data?
this question could mean almost anything. any software program including a function or two dealing with linkage disequilbrium technically meets this definition.
do you have a more specific question? perhaps relating to a given field such as cancer biology?
I'm sorry. Yes in the context of cancer: a tool/database that contains information of the effect that multiple variants will have on the patient disease instead of predicting the consequence for independent variants (like ANNOVAR and VEP).
