В 3 (23 %) из 13 семей семейный анамнез отягощен по кистам почек. Представлена характеристика мутаций генов при кистозных болезнях почек с аутосомно-рецессивным типом наследования у 13 пациентов. Из 21 идентифицированного варианта в генах PKHD1, INVS, NPHP1, TMEM67 у 15 (71 %) обнаружены известные патогенные варианты, у 6 (29 %) — варианты ранее не описанные в базах данных. У 11 детей с фенотипом поликистозной болезни почек с аутосомно-рецессивным типом наследования и фиброзом печени идентифицированы варианты гена PKHD1. Вариант C&gt;T (р.Thr36Met) — самый распространенный среди детей с идентифицированными вариантами мутаций гена PKHD1 при поликистозной болезни почек с аутосомно-рецессивным типом наследования у 5 из 21 (23,8 %), вариант c.664A&gt;G (р.Ile222Val) выявлен у 1 (4,8 %) пациента, c.6992T&gt;A (р.Ile2331Lys) — у 1, c.10444C&gt;T (р.Arg3482Cys) — также у 1. У 3 детей с гомозиготными и компаунд-гетерозиготными патогенными вариантами в генах INVS, NPHP1, TMEM67 подтверждены инфантильный (n = 1) и ювенильный (n = 2) нефронофтиз.</p></sec><sec><title>   Заключение</title><p>   Заключение.

The characteristic of gene mutation in cystic kidney diseases with autosomal recessive type of inheritance in 13 patients is presented (in 2 tables). Of the 21 identified variants in the genes PKHD1, INVS, NPHP1, TMEM67, 15 (71 %) had known pathogenic significance, 6 (29 %) had previously undescribed variants in data-bases. Variants of the PKHD1 gene were identified in 11 children with the phenotype of polycystic kidney disease with autosomal recessive type of inheritance and liver fibrosis. In the study, variant C.107C&gt;T (Thr36Met) is the most common among children with identified variants of the PKHD1 gene in autosomal recessive polycystic kidney disease in 5 out of 21 (23.8 %), c.664A&gt;G (Ile222Val) in 1 (4.8 %), c.6992T&gt;A (Ile2331Lys) in 1 (4.8 %), c.10444C&gt;T (Arg3482Cys) at 1 (4.8 %).
