Additionally, rs17011429, which has strong linkage disequilibrium with rs2553628, was identified as a co-eQTL associated with schizophrenia [29].This allele-specific regulation provides a potential mechanism by which genetic variations at the CNTNAP5 locus could contribute to the development of retinal degeneration, by influencing CNTNAP5 levels during critical stages of retinal development. Here, CNTNAP5 is linked to retinal degeneration.
