Hello,

what is difference between main release e.g. GRCh37 and its patches e.g. GRCh37.p5? Can patching lead to changes in positions ("insertions, deletions") or it is just repairing of wrong bases(substitutions)?

I have some data showing positions of mutations,deletions,transversions,... in GRCh37 and I would like to check whether they were already reported. I know there are databases like COSMIC,SNPdb,dbVar and possibly much more - is there some one-stop shop for this type of data? If possible GRCh37-based and with programatic access.

Thank you for answers
