Scientific Laboratory of Molecular Genetics

Summary of scientific activities on the RSU Research Portal

Accredited medical laboratory according to ISO:15189 standards with an LATAK-633-2020 accreditation certificate, within the framework of which part of its examinations are accredited.

The Scientific Laboratory of Molecular Genetics conducts research on the genetic causes of diseases and their characteristics, especially in the field of rare diseases, the use of biomarkers in diagnostics, and prognosis of the course of diseases.

The laboratory provides students, residents, and doctoral students with the opportunity to develop scientific research.

The laboratory cooperates with various partners both in Latvia (the genome database of the Latvian population, Riga Eastern Clinical University Hospital, the Children's Clinical University Hospital etc.) and abroad (the Academy of Medical Sciences of Ukraine, the Institute of Hereditary Pathology and more).
