Recurrent de novo mutations in CLDN5 induce an anion-selective blood-brain barrier and alternating hemiplegia.

Abstract excerpt

Claudin-5 is the most enriched tight junction protein at the blood-brain barrier. Perturbations in its levels of expression have been observed across numerous neurological and neuropsychiatric conditions; however, pathogenic variants in the coding sequence of the gene have never been reported previously. Here, we report the identification of a novel de novo mutation (c.178G>A) in the CLDN5 gene in two unrelated...
