DYX1C1 E417X

(DYX1C1 Glu417Stop)

Short summary

One study reports this variant to be associated with dyslexia. The study group was relatively small and so the results did not have strong significance. If they are representative this variant is associated with a doubled risk for dyslexia, but it is unclear whether the effect would be additive, dominant, or recessive.

Taipale M, Kaminen N, Nopola-Hemmi J, Haltia T, Myllyluoma B, Lyytinen H, Muller K, Kaaranen M, Lindsberg PJ, Hannula-Jouppi K, Kere J. A candidate gene for developmental dyslexia encodes a nuclear tetratricopeptide repeat domain protein dynamically regulated in brain. Proc Natl Acad Sci U S A. 2003 Sep 30;100(20):11553-8. Epub 2003 Sep 3. PubMed PMID: 12954984; PubMed Central PMCID: PMC208796.

This study reported an association of variants in this gene with dyslexia. The statistical significance of this variant, after Bonferroni correction, is reported as 0.048.

Assuming an incidence of dyslexia of 5%, these numbers imply an attributable increased risk of ~5.2% (about double)
