Add PCSK9 R46L loss-of-function variant (NEJM 2006: OR 0.77 CHD,
0.40 MI) as a protective cardiovascular SNP with negative weights.
Include PCSK9→LDL-C biomarker correlation (15-21% lower LDL in
carriers). Refactor gene-biomarker correlations from match to
additive if-chain so multiple gene effects can stack on the same
biomarker (e.g., APOE raises LDL while PCSK9 R46L lowers it).
Panel expanded to 20 SNPs.
