CACNA1G and dyslexia: Of the 22 genes that had high-impact variants filtered through stringent bioinformatic approaches in at least three dyslexia cases, five genes were validated in the follow-up analysis: CACNA1D, CACNA1G, CLDN3, CNGB1, and CP. Notably, a specific variant (7-73769649-G-A; c.C401T; p.P134L) in the CLDN3 gene was identified in six independent cases, showing a four-fold higher frequency compared to population reference datasets.
