OMIM #611816 or #135500 / ORPHA #3473 or ORPHA #420561

Abstract

KCNH1 missense variants have been associated with syndromic neurodevelopmental disorders, including Zimmermann-Laband syndrome 1, Temple-Baraitser syndrome and, recently, with milder phenotypes as epilepsy.

We want to:

1. collect cross-sectional and longitudinal clinical data from patients with rare heterozygous KCNH1 variants to establish a database of high-quality genetic and clinical data sets.

2. To functionally test the effects of the KCNH1 mutations to study if the variants are pathogenic or not.

3. Establish genotype-phenotype patterns and perform pilot experiments to explore options for rescue pharmacology using existing drugs that target the KCNH1 receptor.
