Cockayne Syndrome
Also known as: CS, Neill-Dingwall syndrome, Weber-Cockayne syndrome
Cockayne syndrome (CS) is a rare, autosomal recessive disorder characterized by growth failure, impaired neurological development, sensitivity to sunlight (photosensitivity), and premature aging. It is caused by mutations in genes involved in DNA repair, specifically the transcription-coupled nucleotide excision repair (TC-NER) pathway.
Cockayne Syndrome is a rare disease where kids grow slowly, are very sensitive to the sun, and have problems with their brains. It's like they're aging too fast. Doctors can help with some of the problems, but there's no cure.

History
Cockayne syndrome was first described in 1936 by Edward Alfred Cockayne, an English physician, who reported two siblings with the characteristic features of the disease.
Recent Breakthroughs
CRISPR-Cas9 Gene Editing for Cockayne Syndrome
Preclinical studies are investigating the potential of CRISPR-Cas9 gene editing to correct mutations in ERCC6 and ERCC8 genes in patient-derived cells. Early results show promising restoration of DNA repair function.
Novel Therapeutic Target Identification
Researchers have identified potential therapeutic targets related to oxidative stress and mitochondrial dysfunction in Cockayne Syndrome. Studies are underway to develop drugs that can mitigate these effects.
