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 β-strand; the plat domain; a disulfide bond; the 'interaction with gpihbp1' region; a UniProt-annotated variant site (in hlpp1; has 48% of normal activity in vitro; decreased levels of activity account for by the lower protein mass levels of the mutants rather than by decreased enzymatic activities; loss of interaction with gpihbp1)
