"The Immortal Gene" is a specialized book that addresses the genetic and epigenetic factors of neurological disorders, particularly dyslexia. In today's world, neurological disorders are one of the leading causes of death. This book analyzes the genetic mutations in the nerves of individuals suffering from dyslexia and examines the role of epigenetic factors in the development of these conditions. The study includes a group of 50 individuals, comprising 10 patients with dyslexia and 10 control subjects. The specific genes DCDC2, KIAA0319, and DYX1C1 are investigated for genetic mutations to gain a better understanding of the relationships between genetics and neurological disorders. The results indicate that dyslexia patients exhibit genetic mutations in the analyzed genes, while no such mutations were found in the control group. This book provides valuable insights into the genetic foundations of neurological disorders and serves as an important resource for professionals and interested readers in this field.
