RESUMO

The work describes the development of a reagent kit for high-performance HLA-typing using the Illumina MiSeq System platform. The developed reagent kit contains all the necessary components for target enrichment of five HLA genes, preparation of libraries, and software for automatic data analysis. The reagent kit verified on a 93 DNA samples with known genotypes. During the verification, the sensitivity and specificity of the reagent kit for each of the HLA loci were determined - for A and B they were 1.0 and 1.0, respectively, for the C-1.0 and 0.99 locus, for the DRB1 locus 0.98 and 0.99, for the DQB1 locus 0.98 and 0.93.

RESUMO

The mucoviscidosis is one of frequent monogenic diseases. In Russia, in case of mucoviscidosis carrying out of DNA-diagnostic is optional. However, its application permits shortening time of diagnosing, increasing efficiency of of therapeutic treatment and preventing secondary manifestation of disease in family. The DNA-diagnostic using panels on frequent mutations in gene CFTR is recommended in cases of uncertain clinical picture and under borderline values of specific laboratory indices. In Russia, application of such panels permit detecting up to 90% of pathological alleles in gene CFTR. To detect more rare alleles the Sanger sequencing is traditionally applied. Lately, highly productive sequencing techniques became available to detect rare mutations. The actual article presents evaluation of efficiency of application of test-system based on technology of target sequencing for detecting mutations unidentified at primary DNA-diagnostic. Besides, in two patients with mucoviscidosis the application of highly productive sequencing techniques permitted to identify previously unknown nonsense mutations Q1038X (c.3112C>T) и W1310X (c.3930G>A).
