Here, we have conducted a replication study by analysing markers previously reported to be associated with dyslexia within the DYX1C1, KIAA0319, DCDC2 and MRPL19/C2ORF3 genes in the Western Australian Pregnancy Cohort (Raine) study, which is a longitudinal cohort for which reading-related measures are available. Here, GCFC2 is linked to dyslexia.
