Assuming the genome build of the input variants is hs37d5.
Switching to the UCSC chromosome-name style from the transcript-centric annotation package.
Chromosome chrM has different lengths between the input VCF and the input TxDb pakage. This chromosome will be discarded from further analysis
Assumming hs37d5 and hg19 represent the same genome build.
Discarding scaffold sequences.
