Advances in genomic medicine accelerate the identification of mutations in disease-associated genes, but the pathogenicity of many mutations remains unknown, hindering their use in diagnostics and clinical decision-making. Predictive AI models are generated to combat this issue, but current tools display low accuracy when tested against functionally validated datasets. We show that integrating detailed conformational data extracted from molecular dynamics simulations (MDS) into advanced AI-based models increases their predictive power. We carry out an exhaustive mutational analysis of the disease gene PMM2 and subject structural models of each variant to MDS. AI models trained on this dataset outperform existing tools when predicting the known pathogenicity of mutations. Our best performing model, a neuronal networks model, also predicts the pathogenicity of several PMM2 mutations currently considered of unknown significance. We believe this model helps alleviate the burden of unknown variants in genomic medicine.
基因组医学的进展加速了疾病相关基因突变的识别,但许多突变的致病性仍然未知,这阻碍了它们在诊断和临床决策中的应用。为解决这一问题而生成了预测性人工智能模型,但目前的工具在针对功能验证数据集进行测试时显示出较低的准确性。我们表明,将从分子动力学模拟(MDS)中提取的详细构象数据整合到先进的基于人工智能的模型中,可以提高其预测能力。我们对疾病基因PMM2进行了详尽的突变分析,并对每个变体的结构模型进行了MDS处理。在这个数据集上训练的人工智能模型在预测突变的已知致病性方面优于现有工具。我们表现最佳的模型,即一个神经网络模型,还预测了目前被认为意义不明的几个PMM2突变的致病性。我们相信这个模型有助于减轻基因组医学中未知变体的负担。
