The Centro Nacional de Genotipado (CeGen) is a technological platform created in 2003 that currently belongs to the "Plataforma de Recursos Biomoleculares-PRB3", one of the "Plataformas de apoyo a la investigación en ciencias y tecnologías de la salud" supported by "Acción Estratégica de Salud-Instituto de Salud Carlos IIII" (CeGen-PRB3-ISCIII ). It has two genotyping units, located at the Centro Nacional de Investigaciones Oncológicas (Madrid) and the Universidade de Santiago de Compostela (Santiago de Compostela) and directed by Dr. Javier Benítez and Dr. Ángel Carracedo, respectively.

Its main goal is to perform large-scale genotyping services -SNPs (Single Nucleotide Polymorphisms), CNVs (Copy Number Variations) and InDels (Insertions and Deletions)- and methylation analysis, both in human and any other species, at high throughput and low cost.

The CeGen-PRB3-ISCIII has highly qualified professionals and the most advanced genotyping platforms -Open Array and TaqMan/Kaspar Genotyping Systems (Applied Biosystems), MassArray system (Agena Bioscience), iScan System (Illumina) and Genechip and GeneTitan technologies (ThermoFisher)-, living in a constant adaptation process to cope with new demands of researchers and companies, both at national and international level.
