More recently, a genome-wide linkage and association scan using ∼133,000 SNPs, in 718 subjects from 101 dyslexia-affected families, reported a borderline significant association with dyslexia status at rs9313548, near FGF18 (5q35.1), which is a gene involved in laminar positioning of cortical neurons during development (Field et al.2013). Here, FGF18 is linked to dyslexia.
