Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.

- a UniProt-annotated variant site (in fvh3; likely pathogenic; decreased protein abundance in homozygous patient cells; results in decreased ligand-activated transcription activator activity; cyp1a1 and cyp1b1 expression levels in homozygous patient cells treated with benzanthracene are reduced compared to controls)
