STRUCTURE OF HEREDITARY AND CONGENITAL PATHOLOGY IN A MULTIDISCIPLINARY SPECIALIZED PEDIATRIC CLINIC: PERSONALIZED APPROACH TO DIAGNOSTICS

Hereditary and congenital pathologies make up a significant proportion in the structure of the general morbidity and mortality of the child population. In this regard, the problem of personalized medical care in multidisciplinary clinical centers seems very urgent. In the Scientific-Practical Center of specialized medical care for children the medical genetic service successfully functions since 1995. In 2017–2019, patients were consulted by geneticists, which accounted for 10,6% of all discharged patients; karyotype studies were performed in 463 (20,4%) consulted patients, chromosomal pathology was revealed in 28 (6,04%) of all karyotyped patients. DNA research was performed in 188 patients: exome sequencing – in 112; sequencing of exons of the SCN1A gene – in 39; search for mutations in the PHOX2B gene – in 17; search for frequent mutations in the FGFR1,2,3 genes – in 15 (the technique was introduced since September 2018); sequencing of SLC2A1 gene – in 5 patients. The high demand for medical genetic counseling and laboratory genetic diagnosis of hereditary and congenital diseases confirms the need for independent medical genetic units in multidisciplinary clinical hospitals, that should interact with medical genetic services at regional and federal levels.
