Так, для дефектов некоторых генов, кодирующих факторы нейрональной миграции, известно сочетание синдрома Кальмана с нейросенсорной тугоухостью, среди пациентов с данным фенотипом чаще других выявляются дефекты в CHD7, SOX10. Однако для дефектов генов факторов нейрональной миграции характерна широкая вариабельность фенотипических проявлений, что связывают с влиянием эпигенетических механизмов. У носителей мутации в пределах одной семьи могут отсутствовать как нерепродуктивные проявления, так и гипогонадизм. В данной статье представлено описание случая синдрома Кальмана у монозиготных близнецов, обусловленного ранее не описанной гетерозиготной мутацией c.462C&gt;G p.I154M в гене SOX10, не ассоциированного с нейросенсорной тугоухостью, унаследованной от отца, имеющего в фенотипе лишь аносмию и не страдающего гипогонадизмом. Мутация выявлена в ходе полноэкзомного секвенирования. Это первое подобное наблюдение в России, указывающее, с одной стороны, на необходимость обследования пациентов с синдромом Кальмана на дефекты SOX10 в числе прочих факторов нейрональной миграции и дифференцировки, с другой стороны — на перспективность проведения полноэкзомного секвенирования в группе пациентов с недифференцированным иГГ.</p></abstract><trans-abstract xml:lang="en"><p>More than 30 genes are known to take part in hypothalamic-pituitary-gonadal axis development at the date and role of more than 10 other genes is studied. Despite it about 50% of isolated hypogonadotropic hypogonadism cases still have no molecular genetic explanation.</p><p>A number of specific associations between iHH and different not-reproductive manifestations called syndromic forms are distinguished in general group of iHH. For example, the combination of Kalmann syndrome with sensorineural hearing loss is known as manifestation for defects of some genes encoding factors of neuronal migration; in patients with this phenotype CHD7, SOX10 genes defects are most frequent. However, defects in the genes of neuronal migration factors are characterized by a wide variability of phenotype, which is explained by the epigenetic mechanisms influence. Carriers of the mutation within the same family may lack some non-reproductive manifestations as well as hypogonadism.</p><p>Here we present a case of Kalmann syndrome in monozygous twins, caused by a previously not described heterozygous mutation c.462C&gt; G: p.I154M in the SOX10 gene in the absence of sensorineural hearing loss. The mutation was inherited from a father who has only isolated anosmia in the phenotype. This mutation was identified during full exome sequencing. This unique observation for Russia shows on the one hand expediency to check SOX10 sequence in addition to the other factors of neuronal migration and differentiation and, on the other hand, the prospect of full exome sequencing in a group of patients with undifferentiated iHH.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нейросенсорная тугоухость</kwd><kwd>синдром Кальмана</kwd><kwd>SOX10</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>deafness</kwd><kwd>Kalmann syndrome</kwd><kwd>SOX10</kwd><kwd>case report</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при содействии Фонда поддержки и развития филантропии «КАФ».
