Polygenic Risk and Association beyond Linearity

Overview

Genomic Ensembling (GenomEn) is an ensemble framework for genotype-to-phenotype prediction that uses both linear and non-linear estimators to capture gene-gene interactions often overlooked by traditional polygenic risk score (PRS) methods. For more informations on the methods, please refer to our paper.

The package enables researchers to improve predictive performance beyond conventional linear PRS approaches by modeling complex genetic interactions. GenomEn also natively supports variants on the X sex chromosome, which are often neglected due to integration challenges with autosomes, further improving predictive performance and simplifying the study of X-linked traits. Finally, GenomEn allows for local and global variant-level interpretability via SHAP values, allowing to gain new insights into complex traits.

Installation

Install from PyPI:

pip install genomen

Install with optional dependency groups:

# Development dependencies (black, pytest, etc.)
pip install genomen[dev]

# GPU support (CUDA 12)
pip install genomen[gpu]

# Deep neural network support
pip install genomen[dnn]

Quick Start

from genomen.data import DataSet, split
from genomen.model import GenomenModel

# Load and split data
dataset = DataSet()
train_set, test_set, val_set = split(dataset)

# Train model
model = GenomenModel()
model.fit(train_set, val_set)

# Make predictions
geno_preds, covar_preds, preds = model.predict(test_set)
