The influence of DCDC2 risk genetic variants on reading: Testing main and haplotypic effects

Research output: Contribution to journalArticle

Abstract

Developmental dyslexia (DD) is a complex neurodevelopmental heritable disorder. Among DD candidate genes, DCDC2 is one of the most replicated, with rs793862, READ1 and rs793842 likely contribute to phenotypic variability in reading (dis)ability. In this study, we tested the effects of these genetic variants on DD as a categorical trait and on quantitative reading-related measures in a sample of 555 Italian nuclear families with 930 offspring, of which 687 were diagnosed with DD. We conducted both single-marker and haplotype analyses, finding that the READ1-deletion was significantly associated with reading, whereas no significant haplotype associations were found. Our findings add further evidence to support the hypothesis of a DCDC2 contribution to inter-individual variation in distinct indicators of reading (dis)ability in transparent languages (i.e., reading accuracy and speed), suggesting a potential pleiotropic effect.
