New high-throughput technologies and, above all, next generation sequencing (NGS) technologies as whole-genome, whole-exome and „Mendeliome“ sequencing have made it easier to discover disease-associated genes and disease-causing mutations. Our MutationMining (MM) Team searches the data generated by NGS-based analyses to detect novel causative genes and mutations in patients with various rare genetic diseases and undiagnosed congenital syndromes.
The MutationMining strategy relies on an innovative bioinformatics pipeline and a multidisciplinary team of clinicians and researchers who collaboratively analyze the data and interpret the relevance of identified variants. This has proven to be a successful approach, leading to the identification of numerous disease-associated genes. In a first national pilot study on the use of “Mendeliome” sequencing (i.e. the NGS-based analysis of 4813 genes) in children with unclear congenital malformation syndromes, we put the MM team strategy into action and were able to establish a molecular diagnosis in 55% of cases (Moosa et al; submitted for publication).
The MM team also aims to establish sustainable clinical and bioinformatics strategies for interpretation of potentially causative variants in whole-genome/exome sequencing, to define standardized procedures and to assure quality standards. Additionally, we work on developing structured and standardized diagnostic algorithms (indication criteria) to perform NGS-based whole-genome/exome sequencing in children and adults with an unclear diagnosis.
