Nükleotid Eksizyon - DNA Tamir Bozuklukları
Özet
Nükleotid eksizyon ve DNA tamir bozuklukları, DNA hasar onarım mekanizmalarının devre dışı kalmasıyla kromozom kırılmalarına ve kanser yatkınlığına yol açan otozomal resesif geçişli hastalıklardır. Bu grupta yer alan Cockayne sendromu, trikotiyodistrofi ve kseroderma pigmentosum, hem santral hem de periferik sinir sistemini etkileyerek çeşitli nörolojik klinik tablolara neden olmaktadır. Genetik kökenli bu hastalıklar, klinik yönetim açısından erken tanı ve kapsamlı destekleyici tedavi stratejilerine ihtiyaç duyar.
Nucleotide excision and DNA repair disorders are autosomal recessive conditions resulting from a failure in DNA damage repair mechanisms, leading to increased chromosomal instability and cancer predisposition. This group includes Cockayne syndrome, trichothiodystrophy, and xeroderma pigmentosum, all of which exhibit significant neurological involvement affecting both the central and peripheral nervous systems. Given their genetic etiology, these disorders necessitate early identification and the implementation of comprehensive supportive management strategies.
