INTRODUCTION.
Dyslexia (DYX) is a disorder manifested by difficulty learning to read despite conventional instruction, adequate intelligence, and sociocultural opportunity. It is among the most common neurodevelopmental disorders, with a prevalence of 5 to 12%.
There is evidence that dyslexia type-2 is caused by mutation in the DYX2 gene on cytogenetic location 6p22-p21 and genomic coordinates 6:15,200,001-46,200,000. The screenshot of the DYX2 gene 31,000,000 bp (base pairs) of DNA sequence length is shown BELOW. Nine (9) other genes besides DYX2 in the 6p22-p21 cytogenetic location are listed BENEATH.
