Genetics and Epigenetics in Neurodegenerative Disorders

Genetics:

Genetics is a subdivision of biology included with the study of genes, genetic variation, and heredity in organisms. Usual disorders, like Parkinson disease & Alzheimer disease, and heterogeneous heritable conditions, include ataxias and spastic paraplegias.

Epigenetics:

Epigenetics is an ongoing field in the light of potential impact on development of neurodegenerative diseases. It is a mechanism independent of DNA sequence with effects on gene transcription, yet in specific way it is heritable.
