In this study, we concurrently investigated 3 possible causes of dyslexia-a phonological deficit, visual stress, and a reduced visual attention span-in a large population of 164 dyslexic and 118 control French children, aged between 8 and 13 years old. We found that most dyslexic children showed a phonological deficit, either in terms of response accuracy (92.1% of the sample), speed (84.

Although an important genetic component is known to have a role in the aetiology of dyslexia, we are far from understanding the molecular mechanisms leading to the disorder. Several candidate genes have been implicated in dyslexia, including DYX1C1, DCDC2, KIAA0319, and the MRPL19/C2ORF3 locus, each with reports of both positive and no replications.

- The study examines how phoneme awareness, rapid naming, and verbal memory relate to dyslexia in children, considering the complexity of written language.
- Testing involved 1,138 control and 1,114 dyslexic children across six languages with varying orthographic complexities.
- Results indicate that phoneme deletion and rapid naming are strong indicators of dyslexia, especially in languages with more complex writing systems, highlighting the role of orthographic complexity in dyslexia symptoms.
