Strong motion deficits in dyslexia associated with DCDC2 gene alteration.
Dyslexia is a specific impairment in reading that affects 1 in 10 people. Previous studies have failed to isolate a single cause of the disorder, but several candidate genes have been reported. We measured motion perception in two groups of dyslexics, with and without a deletion within the DCDC2 gene, a risk gene for dyslexia. We found impairment for motion particularly strong at high spatial f...
متن کاملA dyslexia-associated variant in DCDC2 changes gene expression.
Reading disability (RD) or dyslexia is a common neurogenetic disorder. Two genes, KIAA0319 and DCDC2, have been identified by association studies of the DYX2 locus on 6p21.3. We previously identified a 2445 bp deletion, and a compound STR within the deleted region (BV677278), in intron 2 of DCDC2. The deletion and several alleles of the STR are strongly associated with RD (P = 0.00002). In this...
متن کاملTwo visual motion processing deficits in developmental dyslexia associated with different reading skills deficits.
Developmental dyslexia is associated with deficits in the processing of visual motion stimuli, and some evidence suggests that these motion processing deficits are related to various reading subskills deficits. However, little is known about the mechanisms underlying such associations. This study lays a richer groundwork for exploration of such mechanisms by more comprehensively and rigorously ...
متن کاملDCDC2 gene polymorphisms are associated with developmental dyslexia in Chinese Uyghur children
Developmental dyslexia is a complex reading and writing disorder with strong genetic components. In previous genetic studies about dyslexia, a number of candidate genes have been identified. These include DCDC2, which has repeatedly been associated with developmental dyslexia in various European and American populations. However, data regarding this relationship are varied according to populati...
متن کاملStrong genetic evidence of DCDC2 as a susceptibility gene for dyslexia.
We searched for linkage disequilibrium (LD) in 137 triads with dyslexia, using markers that span the most-replicated dyslexia susceptibility region on 6p21-p22, and found association between the disease and markers within the VMP/DCDC2/KAAG1 locus. Detailed refinement of the LD region, involving sequencing and genotyping of additional markers, showed significant association within DCDC2 in sing...
