bioinformatics investigation and contribution of other chromosomes besides chromosome 21 in the risk of down syndrome development

Introduction: down syndrome as a genetic disorder is a popular research topic in molecular studies. one way to study down syndrome is via bioinformatics. methods: in this study, a gene expression profile from a microarray study was selected for more investigation. results: the study of down syndrome patients shows specific genes with differential expression and network centrality properties. these genes are introduced as rhoa, fgf2, fyn, and cd44, and their level of expression is high in these patients. conclusion: this study suggests that besides chromosomes 21, there are additional contributing chromosomes to the risk of down syndrome development. besides, these genes could be used for clinical studies after more analysis.
