Inheritance of these genes is involved in the etiology (cause) of absence seizure. [1] The commonly held belief is that the genetic factor is the primary cause of childhood absence epilepsy. Furthermore, patients with childhood absence epilepsy have also been reported to exhibit certain copy number variations (CNVs), such as 15q11.2, 15q13.3 ...
The dual-route system could explain the different rates of dyslexia occurrence between different languages (e.g., the consistency of phonological rules in the Spanish language could account for the fact that Spanish-speaking children show a higher level of performance in non-word reading, when compared to English-speakers).
