    Abstract

    Dyslexia is a common learning disability with a known genetic component. Several candidate genes have been implicated in dyslexia susceptibility, such as ROBO1, KIAA0319, and DCDC2. Associations with variants in these genes have also been reported for a variety of psychometric measures that tackle underlying processes that might be impaired in dyslexic people. In this study, we first conducted a literature review to select single nucleotide polymorphisms (SNPs) in dyslexia candidate genes that had been repeatedly implicated in multiple studies. We then assessed the selected SNPs for association in a well-phenotyped longitudinal dataset: the Dutch Dyslexia Program longitudinal sample. We tested for association with several quantitative traits, including word and nonword reading fluency, rapid naming, phoneme deletion and nonword repetition, and took advantage of the longitudinal nature of the sample to examine if associations were stable across four developmental time-points (from 7 to 12 years). Two SNPs in the KIAA0319 gene were found to be nominally associated with rapid naming, and further analysis revealed that these associations were stable across different ages.

    Abstract

    Dyslexia or reading disability is a neurodevelopmental condition with a relatively high prevalence in the population (5 - 10% depending on diagnostic criteria). Typically, reading assessment and diagnosis is focused on children, who are categorized as dyslexic if they have reading difficulties that cannot be explained by other factors such as low IQ or other neurological disorders. Although dyslexia can become milder in adulthood, people often retain lifelong difficulties with reading that may affect training, employment and life choices. Dyslexia usually has a complex and multifactorial background that includes genetic contributions. Some unusual families may have relatively rare forms of the disorder that are caused by single genetic mutations with strong effects on reading ability. Here we have focused on extended families with multiple affected members, which may have these kinds of genetic subforms of the disorder. Word and nonword reading fluency measures have been taken for all family members available. We have evaluated these continuous traits across the generations in order to best discriminate affected from unaffected members. We also propose a genetic strategy focused on sequencing the genomes of key members in order to identify possible risk variants. Genes that are found through this approach may be particularly crucial for the development of normal reading and language skills.
