I'm currently designing a workflow to analyze some exome sequencing data (VCF).
Now, I'd like to add OMIM data and HGMD data to my VCF file.
but I couldn't download some database that include them or find any software to annotate this data online or offline.
Do you know where I could find this kind of data file or which software doing those?
Regards.

Hi Bahar,
We use the recommended tool SnpEff for variant annotation in VCFs, mainly to predict AA changes and effects. We also annotate the ID field with DbSNP using SnpSift (under the same project). However, to my knowledge there's also an option to annotate the VCF with several other clinical databases such as OMIM, check this link: http://snpeff.sourceforge.net/protocol.html
SnpEff: http://snpeff.sourceforge.net/
Hope this helps,
Alon
Another tool that you may find complementary (and which takes snpEff or VEP annotated VCFs as input, and performs additional annotations) is GEMINI. It also transforms the VCF data into a SQLite3 formated database and can contain pedigree information. It has a diverse set of tools to analyze exomes as trios, or select variants that fit specific inheritance patterns, genotype constraints, etc.
