National Biobank of Latvia – Genome Database of Latvian Population

Genome Database of Latvian Population (LGDB) collects, stores, and processes biological samples donated by Latvian citizens for scientific purposes, together with associated medical, lifestyle, and socioeconomic data. It was founded in 2006, and at the moment LGDB stores biological samples and related phenotypic and clinical information from approximately 1.5% of the population of Latvia. By its design, LGDB is a mixed-type biobank, which includes both general population samples and collections of specific disease samples. Disease-specific specimen collections contain specimens from patients suffering from cardiovascular, endocrine, oncological, digestive tract, and various other diseases. The set of standard biological samples is covered in a biobank including DNA, plasma, serum, and leukocytes, however, in the case of individual collections, cancer biopsies, urine, and fecal samples, as well as viral swabs collected as part of COVID-19 research are available. In 2016, Latvia became a member of the European infrastructure consortium BBMRI-ERIC (Biobanks and BioMolecular Resources Infrastructure), and the BMC Genome Center became the contact point of this organization, which provides consultations and support to all Latvian biobanks.

Molecular analyses

The laboratory of the Genome Center provides a wide range of molecular analyzes for the needs of BMC research groups, local and international partners, as well as biotechnology and diagnostic companies. The laboratory provides both manual execution of specific sample processing protocols and bulk sample processing using modern, automated platforms (Tapestation 4200, MGISP100, MGISP960, Tecan® Freedom EVO 100). The equipment of the laboratory premises allows for high-quality processing of low-biomass, unstable, and even potentially infectious samples (BSL-2). The molecular genetics laboratory of the Genome Center is one of the leading providers of next-generation sequencing services in Latvia, ensuring the acquisition of both full genome sequencing data and targeted gene sequences using DNBSEQ-G400, DNBSEQ-T7,MiSeq System, PromethION-24, MinION Mk1B and Mk1D next-generation sequencing platforms. In collaboration with scientists, laboratory specialists improve their skills regularly and implement new next-generation sequencing applications (including single-cell RNA sequencing, metatranscriptome sequencing, and spatial transcriptomics). In addition, the laboratory provides a range of other in-demand molecular biology analyses, including Sanger sequencing, real-time PCR, and digital PCR.
