mvTool v3: Added variant data from 40,000 people, Asians and Sardinians, meta AF reference, new single variant report

Added over mtDNA variant data from over 40,000 people, derived from multiple Asian and other populations. Of note is the Japanese population allele frequency panel of 3,552 individuals (3.5KJPNv2 https://jmorp.megabank.tohoku.ac.jp). 

MSeqDR constructed the meta-population AF reference, which provide position-specific variant information for up to 90,000 people at some positions.

Data was derived from mito-WGS, or from WES (Details in separate text).

For single variant annotation, a new report button supports converting of the annotation into vertical tables for alternative view in different directions.
