Для неё характерны микроцефалия, гипоплазия мозолистого тела, неонатальная мышечная гипотония, сменяющаяся спастичностью, а также тяжелая умственная отсталость. Повторяющийся вариант c.1160_1161del был выявлен у шести пациентов из неродственных неинбредных семей. Был проведен анализ гаплотипов гена AP4B1 у четырех из шести больных на хромосомах с этой мутацией, в результате чего не выявлено единственного гаплотипа, сцепленного с данным вариантом. Таким образом, он может быть, как горячей точкой, так и распространиться в результате эффекта основателя.</p></abstract><trans-abstract xml:lang="en"><p>The reason of SPG47 is homozygous and compound-heterozygous mutations in AP4B1 gene. SPG47 is characterized by microcephaly, corpus callosum hypoplasia, neonatal muscular hypotension, followed by spasticity and severe mental retardation. Variant c.1160_1161del was identified in six patients from unrelated, non-consanguineous families. Was performed haplotype analysis AP4B1 gene for four from six patients on chromosomes with this variant. As a result, there wasn’t found the only haplotype linked to this variant. Therefore, this variant can be a “hot spot” mutation, or could have spread as a result the founder effect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>частый вариант</kwd><kwd>AP4B1</kwd><kwd>эффект основателя</kwd></kwd-group><kwd-group xml:lang="en"><kwd>frequent variant</kwd><kwd>AP4B1</kwd><kwd>the founder effect</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ebrahimi-Fakhari D., Behne R., Davies A.K., Hirst J.
