          Coordinate verification status, genomic context, quality tier and isoform confidence are distinct concepts and are reported separately. Ping-pong pairs and family overlaps are computed per species. SNV / dbSNP / ClinVar / COSMIC annotations are human-only and are not populated for the other-species release.
