Clinical genetic testing has been transformed in recent years by the introduction of Next-Generation Sequencing (NGS). Targeted gene panels have made it possible to simultaneously analyse hundreds of genes with high confidence. However, since current aligners lack the sensitivity to distinguish reads that come from homologous parts of the genome, it is a challenge to work with genes with paralogues or pseudogenes. Pseudogenes arise from duplication of protein-coding genes, and have been considered to be degraded paralogues, due to loss of functionality.

Characterization of a Type 2 diabetes-associated islet-specific enhancer cluster in STARD10 by genome editing of EndoC-βH1 cellsPoster
Genome-wide association studies (GWAS) have identified more than 100 genetic loci associated with type 2 diabetes. The majority of these are located in the intergenic or intragenic regions suggesting that the implicated variants may alter chromatin conformation. This, in turn, is likely to influence the expression of nearby or more remotely located genes to alter beta cell function. At present, however, detailed molecular and functional analyses are still lacking for most of these variants. We recently analysed one of these loci and mapped five causal variants in an islet-specific enhancer cluster within the STARD10 gene locus. Here, we aimed to understand how these causal variants influence b-cell function by alteration of the chromatin structure of enhancer clusterREAD MORE
Psychiatric Risk Gene Cacna1c and Early Life Stress: Potential Gene-Environment interactions?Poster
Early life stress (ELS) is highly associated with development of psychopathology
and mood disorders in adulthood. Genetic studies have identified variation in the gene calcium voltage-gated channel subunit alpha1C (CACNA1C) to increase risk for several psychiatric disorders. This poster assessed the expression of Cacna1c following prepubertal stress.
