Dyslexia susceptibility 1 candidate gene 1 protein is a protein that in humans is encoded by the DYX1C1 gene. This protein contains 420 amino acids with 3 tetratricopeptide repeat (TPR) domains, thought to mediate proteinâÂÂprotein interactions.
A mutation in the DYX1C1 gene has been associated with deficits in reading ability (dyslexia).
