| Reported Trait | LDL cholesterol | 
| Mapped Trait(s) | low density lipoprotein cholesterol measurement (EFO_0004611) | 
| Additional Trait Information | Phenotype defined in GLGC. Please refer the paper for more details. | 
| Score Construction | |
| PGS Name | LDL_AFR_ldpred2 | 
| Development Method | |
| Name | ldpred2 | 
| Parameters | Default parameter setting in bigsnpr version 1.12 -- the proportion of causal SNPs is chosen from a sequence of length 17 that are evenly spaced on a logarithmic scale from 10^(-4) to 1; per-SNP heritability is chosen from 0.7, 1, or 1.4 times the total heritability estimated by LD score regression divided by the number of causal SNPs. "sparse” option = to FALSE. |
