<p>I have a number of VCF files, where each VCF file possesses variant data for a single patient (this is the way Illumina provides their data).  Is it possible to combine all of the data for the patients into one VCF file?  If so, how?  Can I use plink/seq to do this?!  </p>

<p>Any suggestions and leads would be extremely helpful.</p>

Use [vcf-merge](https://vcftools.github.io/perl_module.html#vcf-merge)
