Predicted loss-of-function is descriptive, not an applied PVS1 code.

Population frequency

Grpmax group 8.48e-05% European (non-Finnish) · 1/1,179,934 alleles

Overall 6.2e-05% 1/1,613,578 alleles · very rare exomes 1/1,461,256 · genomes 0/152,322 · joint denominator

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.
