Genotyping/CNV

At the Microarray Core Facility we provide access to full service of state-of-the-art genotyping of customized SNP sets, focused SNP sets, and genome-wide screens covering up to 5.000.000 SNPs on BeadChips (Illumina). Beside standard genotyping, we support loss-of heterocygosity (LOH), and copy number variation (CNV) studies. For the analysis of genetic variation and function, we make use of the Illumina Beadchip technology.

The image features a series of DNA sequences displayed in white text against a gradient background of red, orange, and green. The text includes variations marked by brackets, indicating nucleotide changes within the sequences. The focus is on showcasing the genetic information represented in the sequences.

Genotyping / CNV Analysis

Genotyping provides a measurement of the genetic variation between members of a species. Single nucleotide polymorphisms (SNP) are the most common type of genetic variation. A SNP is a single base pair mutation at a specific locus, usually consisting of two alleles (where the rare allele frequency is >1%; random definition). SNPs are often found to be the etiology of many human diseases. Because SNPs are evolutionary conserved, they have been proposed as a markers for use in quantitative trait loci (QTL) analysis and in association studies. Previously these studies were done using microsatellites.

Genome-wide SNP Analysis

We provide service, using all available Illumina Infinium BeadChips that carry a fixed-content of SNPs for whole genome genotyping screens. This offers virtually unconstrained locus selection for high-value content coupled with high resolution. Until now we've analyzed more than 2000 samples.
