Роль генов семейства TLDc в тяжелых неврологических заболеваниях человека

Аннотация
Неврологические заболевания человека представляют собой обширную группу заболеваний разной степени тяжести, от редких эпилептических приступов и нарушений слуха до тяжелых поражений центральной нервной системы. На данный момент описано большое число генов, мутации в которых приводят к развитию неврологических нарушений, и ярким примером являются гены OXR1 и TBC1D24, члены высококонсервативного семейства TLDc. Гены этого семейства обнаружены у всех эукариотических организмов и характеризуются наличием консервативного TLDc домена с неизвестной молекулярной функцией. Было показано, что все гены семейства TLDc играют важную роль в защите от окислительного стресса, в особенности в клетках центральной нервной системы, а также способны регулировать функцию везикулярной АТФазы, влияя на внутрипросветный pH в различных мембранных органеллах. На сегодняшний день описано большое количество пациентов с патогенными вариантами в гене TBC1D24, приводящими к различным формам эпилепсии, потере слуха, а также тяжелым синдромам, таким как DOORS. За последние несколько лет было также описано несколько пациентов с патогенными вариантами в гене OXR1 с тяжелыми неврологическими нарушениями, включающими микроцефалию, нейродегенерацию и глубокую задержку психического развития. В данном обзоре кратко изложены функции белков данного семейства и ассоциированные с нарушением их функции фенотипы модельных организмов, а также подробно разбирается связь различных вариантов в генах семейства TLDc с заболеваниями человека.
