Врожденные пороки сердца диагностированы в 96–100 % случаев. В большинстве случаев это функционально единственный желудочек сердца с атрезией/стенозом крайней степени легочного ствола. У пробандов выявлены мутации в генах, участвующих в формировании (функционировании) цилий, что позволяет отнести представленные наблюдения к цилиопатиям с аутосомно-рецессивным (CFAP300: c.198_200delinsCC гомозигота, LRRCC1: c.2686dup, c.2650C&gt;A, BBS7: c.1967_1968delinsC, c.454T&gt;C) и сцепленным с полом (ZIC3: c.842_843del) типом наследования.

Congenital heart defects are diagnosed in 96-100 % of cases. In most cases, this is a functionally single ventricle of the heart with atresia/stenosis of the extreme degree of the pulmonary trunk. Mutations in genes involved in the formation (functioning) of cilia were identified in the genome of probands, which allows us to classify the presented cases as ciliopathies with an autosomal recessive (CFAP300: c.198_200delinsCC homozygote, LRRCC1: c.2686dup, c.2650C&gt;A, BBS7: c.1967_1968delinsC, c.454T&gt;C) or sex-linked (ZIC3: c.842_843del) type of inheritance. Heterotaxy syndrome has been described for the first time as part of Bardet-Biedl syndrome.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром гетеротаксии</kwd><kwd>ZIC3</kwd><kwd>CFAP300</kwd><kwd>LRRCC1</kwd><kwd>BBS7</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heterotaxy syndrome</kwd><kwd>ZIC3</kwd><kwd>CFAP300</kwd><kwd>LRRCC1</kwd><kwd>BBS7</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Республиканский бюджет</funding-statement><funding-statement xml:lang="en">Republican budget</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Лазаревич А.А.
