DONSON and FANCM associate with different replisomes distinguished by replication timing and chromatin domain
Eukaryotic replisomes are multiprotein complexes. Here the authors reveal two distinct stressed replisomes, associated with DONSON and FANCM, displaying a bias in replication timing and chromatin domain
The Cockayne Syndrome Natural History (CoSyNH) study:clinical findings in 102 individuals and recommendations for care
Purpose:
Cockayne syndrome (CS) is a rare, autosomal-recessive disorder characterized by microcephaly, impaired postnatal growth, and premature pathological aging. It has historically been considered a DNA repair disorder; fibroblasts from classic patients often exhibit impaired transcription-coupled nucleotide excision repair. Previous studies have largely been restricted to case reports and small series, and no guidelines for care have been established.
Methods:
One hundred two study participants were identified through a network of collaborating clinicians and the Amy and Friends CS support groups. Families with a diagnosis of CS could also self-recruit. Comprehensive clinical information for analysis was obtained directly from families and their clinicians.
Results and Conclusion:
We present the most complete evaluation of Cockayne syndrome to date, including detailed information on the prevalence and onset of clinical features, achievement of neurodevelopmental milestones, and patient management. We confirm that the most valuable prognostic factor in CS is the presence of early cataracts. Using this evidence, we have created simple guidelines for the care of individuals with CS. We aim to assist clinicians in the recognition, diagnosis, and management of this condition and to enable families to understand what problems they may encounter as CS progresses
ATM and CDK2 control chromatin remodeler CSB to inhibit RIF1 in DSB repair pathway choice
Cockayne syndrome group B protein (CSB) is a multifunctional chromatin remodeler involved in double-strand break repair. Here the authors investigate the molecular post-translational signals regulating CSB activity
