| # evals_complex_traits |
|
|
| Variant-effect-prediction benchmark of UKBB fine-mapped complex-trait SNVs vs |
| low-PIP SNVs, 1:9 matched within consequence categories on `(chrom, |
| consequence_final)` plus subset-targeted distance bins, with MAF entering as |
| a continuous matching feature. |
| |
| ## Description |
| |
| | | | |
| |---|---| |
| | Positives | UKBB SuSiE+FINEMAP fine-mapped variants with max(PIP) > 0.9 across 119 traits | |
| | Negatives | max(PIP) < 0.01 across 119 traits, 1:9 matched per positive | |
| | Genome build | GRCh38 (lifted from hg19) | |
| | Variant type | SNVs only | |
| | Coordinates | 1-based (`pos` is 1-based; `ref`/`alt` are single bases) | |
| | Matching ratio | 1:9 | |
| |
| ## Splits |
| |
| | Split | Variants (pos + 9·neg) | Positives | Chromosomes | |
| |---|---:|---:|---| |

| | `test` | 10,000 | 1,000 | even: 2, 4, …, Y | |
| | **total** | **21,630** | **2,163** | | |
| |

| | `distance_tss_pc`, `distance_tss_nc`, `distance_tss` | int | Distances to nearest protein-coding / non-protein-coding TSS (and min, used for `consequence_group` recategorization) | |
| | `tss_closest_pc_gene_id`, `tss_closest_nc_gene_id`, `tss_closest_gene_id` | str | Ensembl gene IDs (passthrough — gene-id was *not* used in matching) | |

|
| ## Matching design |
|
|
| Matching is exact on every categorical key, then Euclidean-nearest on the |
| (RobustScaler-scaled) continuous features as a within-group tie-breaker. |
| Without replacement, k=9. |
|
|
| - **Continuous features**: `distance_tss_pc`, `distance_tss_nc`, `distance_exon_pc`, `distance_exon_nc`, `MAF`. |
| - **Categorical features**: |
| - `chrom`, `consequence_final` |
| - `distance_tss_pc_bin` — `tss_proximal`: edges `[0, 100, 1000, ∞]`; `BIN_NA` elsewhere |
| - `distance_exon_pc_bin` — |
| - `tss_proximal`: edges `[0, 100, 1000, ∞]` |
| - `splicing`: edges `[0, 5, 30, ∞]` |
| - `BIN_NA` elsewhere |
|
|
| Gene-ID columns are kept as passthrough metadata but **not** used as match |
| keys. |
|
|
| ## Matched-feature AUPRC diagnostic |
|
|
| Each continuous matching feature `f` is scored as a single-feature predictor |
| within each subset: `{f}_auprc = max(AP(label, +f), AP(label, −f))`. |
| **Baseline = 0.1 for 1:9 matching**. |
