Herediter Ataksilere Genetik Yaklaşım
Özet
Herediter ataksiler, genetik ve klinik heterojenlikleri nedeniyle tanı konulması zor bir grup bozukluktur. Friedreich ataksisi (FRDA) gibi yaygın formlar ve diğer ataksi türleri, tanı sürecinde öncelikle tekrar dizisi ekspansiyon analizlerini gerektirir. Hastalığın genetik nedenini belirlemek, uygun prognoz tahmini ve etkili bir genetik danışmanlık süreci için kritik öneme sahiptir. Multigenik paneller ve tüm ekzom dizileme (WES) gibi ileri tanı teknikleri, doğru teşhis ve aile yönetimi için temel araçları oluşturur.
Hereditary ataxias present significant diagnostic challenges due to their substantial genetic and clinical heterogeneity. Common forms such as Friedreich's ataxia (FRDA) necessitate initial screening for repeat expansion mutations before proceeding to broader genetic testing. Identifying the specific genetic cause is crucial for determining prognosis and providing effective genetic counseling. Advanced diagnostic strategies, including multigenic panels and whole-exome sequencing (WES), are essential tools for managing these complex conditions and informing familial risk assessment.
