To mitigate the impacts of AMR, it is important to identify the molecular mechanisms of AMR and thereby determine optimal therapy as early as possible. Conventional machine learning-based drug-resistance analyses assume genetic variations to be homogeneous, thus not distinguishing between coding and intergenic sequences. In this study, we represent genetic data from Mycobacterium tuberculosis as a graph, and then adopt a deep graph learning method\u2014heterogeneous graph attention network (\u2018HGAT\u2013AMR\u2019)\u2014to predict anti-tuberculosis (TB) drug resistance. The HGAT\u2013AMR model is able to accommodate incomplete phenotypic profiles, as well as provide \u2018attention scores\u2019 of genes and single nucleotide polymorphisms (SNPs) both at a population level and for individual samples. These scores encode the inputs, which the model is \u2018paying attention to\u2019 in making its drug resistance predictions. The results show that the proposed model generated the best area under the receiver operating characteristic (AUROC) for isoniazid and rifampicin (98.53 and 99.10%), the best sensitivity for three first-line drugs (94.91% for isoniazid, 96.60% for ethambutol and 90.63% for pyrazinamide), and maintained performance when the data were associated with incomplete phenotypes (i.e. for those isolates for which phenotypic data for some drugs were missing). We also demonstrate that the model successfully identifies genes and SNPs associated with drug resistance, mitigating the impact of resistance profile while considering particular drug resistance, which is consistent with domain knowledge.<\/jats:p>","DOI":"10.1093\/bib\/bbab299","type":"journal-article","created":{"date-parts":[[2021,7,16]],"date-time":"2021-07-16T11:13:48Z","timestamp":1626434028000},"source":"Crossref","is-referenced-by-count":19,"title":["An
