    Abstract:
    The study aimed to search for mutations in the ATP7B gene using massively parallel sequencing in patients with Wilson disease in the Tomsk region. For 42 patients with suspected Wilson's disease (aged from 1 to 33 years) was performed molecular genetic analysis. Enrichment of the interest genome regions was carried out by the long-range PCR. DNA libraries with ligated adapters were constructed with Nextera DNA Flex (Illumina, USA) kit. Sequencing was performed on the Illumina MiSeq platform (Illumina, USA). As a result of this work, we identified 9 pathogenic genetic variants. All variants were previously described in the literature and were found in patients with Wilson's disease. Five missense mutations, one splice site mutation, and 3 frameshift mutations were identified. In patients with Wilson's disease in the Tomsk region, the most common variant was c.3207C>A, this variant is the most common both in the Russian Federation and in other European populations. Also, a pathogenic variant c.3036dupC was found, which is probably endemic to the Russian Federation.
