Cockayne syndrome A
A rare disorder characterized by cutaneous sensitivity to sunlight, abnormal and slow growth, cachectic dwarfism, progeroid appearance, progressive pigmentary retinopathy and sensorineural deafness. There is delayed neural development and severe progressive neurologic degeneration resulting in intellectual disability. Two clinical forms are recognized: in the classical form or Cockayne syndrome type 1, the symptoms are progressive and typically become apparent within the first few years or life; the less common Cockayne syndrome type 2 is characterized by more severe symptoms that manifest prenatally. Cockayne syndrome shows some overlap with certain forms of xeroderma pigmentosum. Unlike xeroderma pigmentosum, patients with Cockayne syndrome do not manifest increased freckling and other pigmentation abnormalities in the skin and have no significant increase in skin cancer.

A Robust Methodological Framework for Generating Whole-Brain and Cortical Organoids From Diverse Healthy- and Patient-Derived Induced Pluripotent Stem Cell Lines.
Patient-derived neural organoids (NOs) have emerged as powerful tools for modeling human neurodevelopmental disorders, especially when animal models are unavailable or fail to recapitulate human-specific cortical development. However, significant variability in differentiation potential, even among healthy donor lines, and especially in fragile patient-derived induced pluripotent stem cells (iPSCs), poses major methodological challenges. Protocols that succeed in one line may fail in others, leading to poor organoid formation, reduced growth, impaired neuroepithelial patterning, or complete failure to generate neural tissues. By systematically comparing multiple published protocols, we identified key sources of variability and ultimately developed optimized protocols for generating both whole-brain (WB) and cortical organoids (CO) from human iPSCs (hiPSCs), including lines from progeroid Cockayne syndrome patients. Through iterative refinement of critical parameters, including cell seeding density, Matrigel incorporation, and timing and type of pathway inhibition, we achieved consistent organoid growth and structural organization across all tested lines. The resulting pipeline is adaptable and can be further tailored for newly derived or particularly challenging hiPSC lines. Collectively, this methodological framework enables robust and reproducible generation of NOs from genetically diverse hiPSC sources, providing a reliable platform for studying human neurodevelopment and disease mechanisms in progeroid and other patient-specific contexts.
ercc6 deficient zebrafish exhibit UV and metronidazole sensitivity, increased oxygen consumption, and impaired hair cell mechanoelectrical transduction which can be restored by the superoxide dismutase mimetic MnTBAP.
Cockayne Syndrome is an ultra-rare premature aging condition associated with UV sensitivity, neurocognitive decline, retinopathy, metronidazole-induced lethality, and sensorineural hearing loss. In 70% of affected patients, bi-allelic pathogenic variants in ERCC6 are identified. Although the role of ERCC6 in DNA damage repair has been studied, little is known about the mechanism for defective ERCC6 function in clinical findings, particularly hearing loss. To identify the mechanism of disease caused by pathogenic variants in ERCC6, we developed a zebrafish (Danio rerio) ercc6 loss of function model. We assessed survival after UV and metronidazole exposure, measured basal respiration rates, and evaluated mechanoelectrical transduction function and counts of lateral line hair cells. We found that UV exposure significantly reduces ercc6-/- larval viability. Metronidazole treatment results in complete lethality; wildtype controls show nearly complete survival. ercc6-/- embryos have significantly increased oxygen consumption, suggesting abnormal mitochondrial function. Phalloidin staining of lateral line hair cells with and without UV treatment shows no difference in hair cell counts per neuromast between treatment groups. Mechanoelectrical transduction function after UV exposure, measured by FM1-43 uptake, is reduced. Metronidazole lethality is reduced, oxygen consumption rates are restored, and mechanoelectrical transduction function is preserved by treatment with Mn(III)tetrakis(4-benzoic acid)porphyrin Chloride (MnTBAP), a superoxide dismutase mimetic. We propose that defective mitochondrial function and increased reactive oxygen species levels provide a mechanism for hair cell dysfunction in this model of Cockayne Syndrome. These results provide a foundation for further experiments to explore disease mechanisms and treatment modalities for this premature aging condition.
Mechanisms of transcription-coupled repair and DNA damage surveillance in health and disease.
RNA polymerase II (Pol II)-mediated gene transcription is frequently disrupted by DNA damage from various sources. Transcription-blocking DNA lesions hinder the progression of elongating Pol II, leading to transcription stress that, if unresolved, causes cellular dysfunction, neurodegeneration and ageing. In this Review, we discuss how different types of lesion are recognized by obstructing Pol II and removed by the intricate transcription-coupled nucleotide excision repair (TC-NER) pathway, emphasizing recent structural findings that reveal key aspects of the TC-NER mechanism. We also discuss the mechanisms proposed for processing lesion-stalled Pol II, which is crucial to facilitate TC-NER, and focus on how Pol II ubiquitylation orchestrates repair-complex assembly and Pol II degradation. In addition, we discuss the alternative mechanism of transcription-coupled DNA-protein crosslink repair, which was recently identified to be important for resolving DNA-protein crosslinks in active genes. Finally, we describe how these insights elucidate the different pathological causes of hereditary TC-NER deficiencies, namely of the mild cutaneous ultraviolet-sensitive syndrome and the severe progeroid Cockayne syndrome.
Metronidazole-Induced Hepatotoxicity in Children with Cockayne Syndrome.
[Cockayne syndrome: peculiarities of clinical manifestations and algorithm of observation in childhood].
Cockayne syndrome is an ultra-rare (1:2.5 million) hereditary disease from the group of progeroid syndromes caused by pathogenic and probable-pathogenic variants in DNA repair genes (ERCC8, ERCC6, XPB (ERCC3), XPD (ERCC2) and XPG (ERCC5)) and characterized by abnormal photosensitivity, congenital cataract, microcephaly, sensorineural hearing loss, nervous system pathology and other multisystem changes. In this manuscript, for the first time in the Russian Federation, we present the results of a clinical and genetic study and follow-up of a Russian cohort of patients. During 2 years, from 2023 to 2025, 7 patients with Cockayne syndrome (4 girls and 3 boys) aged from 3 years 11 months to 16 years 3 months were under clinical observation, of whom 3 patients were diagnosed with Cockayne syndrome type A (causative variants in ERCC8 gene) and 4 patients with type B (causative variants in ERCC6 gene). All patients underwent a comprehensive multidisciplinary examination with evaluation of the results of laboratory and instrumental methods of investigation. Based on observational data, we confirmed the incomplete correlation between genotype and phenotype previously described in the literature. With the genotype of Cockayne syndrome type B, previously correlated with severe course of the disease, only one patient had a severe course of the syndrome, two patients had a moderate course, and one patient had a mild course, indicating the variability of the clinical picture within a single gene lesion, and the severity of the course correlated rather with the age of the disease debut: early onset (before 1 year of age) was associated with faster disease progression. Also, regardless of the genotype and severity of the disease course, major diagnostic criteria were identified in all patients: congenital cataract was diagnosed in 5 of 7 observed patients, sensorineural hearing loss in two patients of moderate and mild course of the disease, progressive pathology of the nervous system in 6 of 7 patients, and microcephaly was diagnosed in all patients. This study expands our understanding of the natural course of Cockayne syndrome and our knowledge of the variability of clinical manifestations and severity of the disease course within a single gene lesion. Timely diagnosis and personalized approach of a multidisciplinary team of specialists can slow the progression of complications and improve the quality of life of patients. The work is of value for physicians of various specialties involved in the diagnosis and treatment of orphan genetic diseases, as well as researchers studying the mechanisms of DNA repair and premature aging. ОБОСНОВАНИЕ. Синдром Коккейна — ультраредкое (1:2,5 млн) наследственное заболевание из группы прогероидных синдромов, обусловленное патогенными и вероятнопатогенными вариантами в генах репарации ДНК (ERCC8, ERCC6, XPB (ERCC3), XPD (ERCC2) и XPG (ERCC5)) и характеризующееся аномальной фоточувствительностью, врожденной катарактой, микроцефалией, нейросенсорной тугоухостью, патологией нервной системы и другими мультисистемными изменениями. В данной рукописи, впервые в Российской Федерации, представлены результаты клинико-генетического исследования и наблюдения за российской когортой пациентов. МАТЕРИАЛЫ И МЕТОДЫ. В течение 2 лет, с 2023 по 2025 гг., под клиническим наблюдением находились 7 пациентов с синдромом Коккейна (4 девочки и 3 мальчика) в возрасте от 3 лет 11 месяцев до 16 лет 3 месяцев, из них у 3 пациентов был диагностирован синдром Коккейна типа А (причинные варианты в гене ERCC8), у 4 пациентов — тип В (причинные варианты в гене ERCC6). Всем пациентам проводилось комплексное мультидисциплинарное обследование с оценкой результатов лабораторных и инструментальных методов исследования. РЕЗУЛЬТАТЫ. По данным наблюдений, нами подтверждена неполная корреляция между генотипом и фенотипом, описанная ранее в литературе. При генотипе синдрома Коккейна типа В, ранее коррелирующего с тяжелым течением заболевания, только у одного пациента наблюдалось тяжелое течение синдрома, у двух — умеренной степени, у одного пациента — легкое течение, что свидетельствует о вариабельности клинической картины в рамках поражения одного гена, а тяжесть течения коррелировала скорее с возрастом дебюта заболевания: раннее начало (до 1 года) ассоциировалось с более быстрым прогрессированием заболевания. Также, вне зависимости от генотипа и степени тяжести течения заболевания, большие диагностические критерии были выявлены у всех пациентов: врожденная катаракта была диагностирована у 5 из 7 наблюдаемых пациентов, нейросенсорная тугоухость — у двух пациентов умеренного и легкого течения заболевания, прогрессирующая патология нервной системы — у 6 пациентов из 7, микроцефалия была диагностирована у всех пациентов. ЗАКЛЮЧЕНИЕ. Проведенное исследование расширяет понимание естественного течения синдрома Коккейна и наши знания о вариабельности клинических проявлений и тяжести течения заболевания в рамках поражения одного гена. Своевременная диагностика и персонализированный подход мультидисциплинарной команды специалистов способны замедлить прогрессирование осложнений и улучшить качество жизни пациентов. Работа представляет ценность для врачей различных специальностей, занимающихся диагностикой и лечением орфанных генетических заболеваний, а также исследователей, изучающих механизмы репарации ДНК и преждевременное старение.
