from Part II - Cross-Linguistic Perspectives on Developmental Dyslexia
Published online by Cambridge University Press: 27 September 2019
Developmental dyslexia is a neurologically based learning disorder that often runs in families (Fisher & DeFries, 2002). This chapter focuses on its intergenerational transmission, which refers to the transfer of traits and behaviors from parents to offspring, including genetic factors and nongenetic factors such as epigenetics and environment. Traditionally, transmission of genomic information (i.e., inheritance of DNA sequence) has been considered to be the key pathway by which behavior, cognitive abilities, character traits, and susceptibility to a disorder are inherited. However, growing evidence suggests that nongenetic factors play important roles in influencing gene function and modifying heritability. Combined, the effects of these factors likely result in the various phenotypes of dyslexia. Delineating the intergenerational transmission patterns of dyslexia provides means to further understand its etiology and may provide insight into early identification and preventive intervention.
