evoeval

A collection of genomic variant-effect evaluation datasets. Each dataset is a table of variants keyed on GRCh38 coordinates with a label and annotation columns, stored as Parquet. This repo holds the base (unscored) variant tables — model delta scores are computed downstream, not shipped here.

Standard column schema

Every parquet has these coordinate columns with standardized types:

Column	Type	Description
chrom	str	Chromosome, GRCh38, always chr-prefixed (e.g. chr1, chrX)
pos	int64	1-based VCF position
ref	str	Reference allele
alt	str	Alternate allele

Most datasets are also annotated with:

Column	Type	Description
genomic_element	str	Coarse location: CDS / splice_site / 5UTR / 3UTR / intron / ncRNA / intergenic
consequence	str	Most-severe SnpEff SO term from MANE Select transcripts (except where a dataset carries its own scheme — see per-dataset notes)
variant_type	str	SNV / insertion / deletion / MNV (derived from ref/alt lengths)

omim, gnomad_balanced, and the TraitGym sets carry their own pre-annotation scheme for consequence / genomic_element — see the individual sections.

Positive class: classification = "Splice-altering" Negative class: classification = "Normal" Class balance: 7,147 positive : 4,831 negative. All variants are SNVs.

cosmic.parquet — COSMIC somatic mutations vs neutral variants

Eval task: Distinguish COSMIC-catalogued somatic cancer mutations from common neutral variants. Positive class: label = True — COSMIC-catalogued somatic cancer mutation Negative class: label = False — common benign missense variant (gnomAD, AF > 5%) Class balance: 183 positive : 18,720 negative (102:1)

Column	Type	Notes
chrom	str	chr-prefixed
pos	int64
ref	str
alt	str
label	bool	Label: True = COSMIC cancer mutation
consequence	str	SnpEff most-severe SO term
genomic_element	str	SnpEff coarse element
variant_type	str	All SNV

Important caveat: 180 of 183 positives (98%) are missense_variant in CDS. All other genomic_element/consequence strata have 0 or 3 positives. Stratified AUCs will mostly return None; the overall AUC is the meaningful metric here.

Stratification

• genomic_element — only CDS (180 pos) and intergenic (3 pos) have any positives.
• consequence — only missense_variant (180 pos) and intergenic_region (3 pos) have positives.

omim.parquet — OMIM disease-associated variants vs common variants

Eval task: Distinguish OMIM-listed regulatory disease variants from common population variants. Positive class: label = True — OMIM-curated pathogenic regulatory variant Negative class: label = False — common variant (gnomAD, AF > 5%) Class balance: 406 positive : 2,640,266 negative (6,500:1)

Column	Type	Notes
chrom	str	chr-prefixed
pos	int64
ref	str
alt	str
label	bool	Label: True = OMIM disease-associated
consequence	str	Custom OMIM categories (not SnpEff SO terms)
variant_type	str	All SNV
genomic_element	str	Mapped from custom consequence (see below)

Custom consequence values and their genomic_element mapping:

consequence	genomic_element	n total	n pos
Enhancer	intergenic	2,357,316	37
ncRNA	ncRNA	137,330	60
3' UTR	3UTR	68,413	38
Promoter	intergenic	62,575	130
5' UTR	5UTR	15,030	133
MicroRNA Gene	ncRNA	5	5
Imprinting Control Region	intergenic	3	3

All variants are non-coding regulatory elements. The Enhancer category dominates (89% of rows) with very sparse positives (37 of 2.36M).

Stratification

• genomic_element — 4 strata, all ≥20 rows with both classes: intergenic (170 pos), ncRNA (65), 3UTR (38), 5UTR (133).
• consequence — 5 valid strata: Enhancer (37), ncRNA (60), 3' UTR (38), Promoter (130), 5' UTR (133).

gnomad_balanced.parquet — gnomAD balanced benchmark

Eval task: General variant-effect prediction benchmark using gnomAD population variants. Positive class: label = True — rare variant (singleton in gnomAD, under purifying selection) Negative class: label = False — common variant (AF > 5% in gnomAD, likely neutral) Class balance: 5,996,146 : 5,996,138 (perfectly balanced, 50:50)

Label semantics (GPN-star paper, Benegas et al. 2024): True = gnomAD singleton; False = common variant (AF > 5%). Purifying selection keeps deleterious variants rare, so rare variants are enriched for functional/deleterious effect. A model with signal assigns more negative delta scores to singletons than to common variants.

Column	Type	Notes
chrom	str	chr-prefixed
pos	int64
ref	str
alt	str
label	bool	Label: True/False (see note above)
consequence	str	Simplified consequence terms (see below)
variant_type	str	All SNV
genomic_element	str	Mapped from simplified consequence

Simplified consequence values and their genomic_element mapping (top strata):

consequence	genomic_element	n total	n pos	n neg
intron	intron	6,481,608	3,240,804	3,240,804
intergenic	intergenic	4,714,558	2,357,279	2,357,279
non_coding_transcript_exon	ncRNA	274,540	137,270	137,270
3_prime_UTR	3UTR	136,750	68,375	68,375
downstream_gene	intergenic	129,544	64,772	64,772
upstream_gene	intergenic	124,890	62,445	62,445
synonymous	CDS	37,948	18,974	18,974
missense	CDS	37,452	18,726	18,726
5_prime_UTR	5UTR	29,794	14,897	14,897
splice_region	splice_site	24,170	12,085	12,085

Consequence terms are simplified (not standard SO format): intron not intron_variant, missense not missense_variant. Perfectly balanced within every stratum (pos/neg equal or off by 1).

Stratification

• genomic_element — 7 strata, all perfectly balanced and ≥20 rows.
• consequence — 13 valid strata, all perfectly balanced.

TraitGym (traitgym/)

Source: songlab/TraitGym on HuggingFace. Eval task: Distinguish causal variants from matched controls selected within the same functional category with similar MAF and LD score — the model cannot win on consequence or frequency bias alone. Positive class: label = True (causal variant) Negative class: label = False (matched control)

Annotation: Pre-annotated by the TraitGym authors using ENCODE regulatory-element categories (dELS, pELS, PLS, …) combined with SO terms — these are kept as-is (SnpEff annotation is deliberately not applied, as it would overwrite the informative ENCODE categories).

Consequence categories used:

Term	Meaning
PLS	Promoter-like signature (ENCODE cRE)
pELS	Proximal enhancer-like signature
dELS	Distal enhancer-like signature
pELS_flank, dELS_flank	Flanking regions of ELS elements
intron_variant, intergenic_variant, non_coding_transcript_exon_variant, 3_prime_UTR_variant, 5_prime_UTR_variant, upstream_gene_variant	SO terms

complex_traits.parquet — GWAS fine-mapped non-coding variants

Eval task: GWAS fine-mapped causal non-coding variants vs matched controls. Class balance: 1,140 causal : 10,260 controls (1:9)

Column	Type	Notes
chrom	str	chr-prefixed
pos	int64
ref	str
alt	str
pip	float64	Posterior inclusion probability (causal prior)
trait	str	GWAS trait name (empty string "" for controls)
label	bool	Label: True = causal
maf	float64	Minor allele frequency
ld_score	float64	LD score
consequence	str	ENCODE/SO category (see above)
tss_dist	int64	Distance to nearest transcription start site
match_group	str	Matching group ID (each causal paired with controls)

trait is empty string for all controls — per-trait stratification would create causal-only strata, so it is excluded from stratification.

Stratification

• consequence — 15 valid strata: dELS (314 pos), intron_variant (190), dELS_flank (167), intergenic_variant (103), pELS (101), … Each stratum keeps the 1:9 pos:neg ratio by design.

Column	Type	Notes
chrom	str	chr-prefixed
pos	int64
ref	str
alt	str
OMIM	str	OMIM gene/disease ID (NaN for controls)
consequence	str	ENCODE/SO category (see above)
label	bool	Label: True = disease-causing
tss_dist	int64	Distance to nearest TSS
match_group	str	Matching group ID

Stratification

• consequence — 11 valid strata: 5_prime_UTR_variant (114 pos), non_coding_transcript_exon_variant (71), PLS (63), 3_prime_UTR_variant (29), upstream_gene_variant (21), … Smaller counts — some strata will have low power.
