Pathogenic Genes for Congenital Microtia: A Bioinformatics Analysis

The purpose of this study is to accurately find the pathogenic genes of congenital microtia, so as to lay a theoretical foundation for genetic screening, diagnosis, and gene therapy of congenital microtia in the further stage.In this study, the authors used public data from the Mouse Genome Informatics database. The authors used the String database ( https://string-db.org/ ) to construct the Protein-Protein Interaction network. Then Gene Ontology classification and Kyoto Encyclopedia of Genes and Genomes pathway analysis were performed for the pathogenic genes.The authors searched the Mouse Genome Informatics database and found 84 pathogenic genes of congenital microtia. The Protein-Protein Interaction network for pathogenic genes was constructed, which contained 81 nodes and 148 lines with MCM5, CDT1, POLA1, CDC45, CDC6, EFTUD2, ORC1, ORC4, ORC6, and TCOF1 . The authors conducted a Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis on pathogenic genes, and the results showed that pathogenic genes were involved in O-mannan biosynthesis, cell cycle, RNA polymerase, and other signaling pathways.The authors' results indicated that the occurrence of congenital microtia is attributed to a variety of genes. Furthermore, the interactions of pathogenic genes were further elucidated by using a bioinformatics approach. This study will help to reveal the pathogenesis of congenital microtia and lay the foundation for accurate diagnosis and treatment of congenital microtia in the future.
