Alzheimer Hastalığının Genetiği ve Epigenetiği

Yaşlanma döneminde görülen en yaygın bunama sebeplerinden birisi Alzheimerdır hastalığıdır. Alzheimer hastalığı genetiğinde rol oynayan, amiloid prekürsör protein (APP), presenilin 1 (PSEN1), presenilin 2 (PSEN 2) genleri erken başlangıçlı otozomal dominant Alzheimerdan sorumludur. Daha yaygın olan kompleks geç başlangıçlı Alzheimerdan apolipoprotein E (APO E) kodlayan genin 3 alleli temel genetik risk faktörü olarak bilinir. Alzheimer hastalığı birden fazla yolakta, pek çok seviyede bozukluk içeren kompleks nörodejeneratif bir hastalıktır. DNA metilasyonu ve histon modifikasyonlarını içeren epigenetik değişiklikler, bu yolakları kontrol eden temel düzenleyici mekanizmalar arasındadır

Genetics and Epigenetics of Alzheimer Disease

Alzheimer’s disease is the most common cause of dementia in elderly. Alzheimer’s disease the role of genetics in amyloid precursor protein (APP), presenilin 1 (PSEN1) and presenilin 2 (PSEN2) are responsible for early-onset autosomal dominant Alzheimer disease. For the more common complex late-onset Alzheimer disease, the 3 allele of the gene encoding apolipoprotein E (APOE ) has been recognized as a major genetic risk factor. Alzheimer’s disease is a complex neurodegenerative disorder involving dysregulation of many biological pathways at multiple levels. Epigenetic changes, including DNA methylation and histone modifications are among the major regulatory elements that control these pathways
