Targeted gene under study:

WDR13 (OMIM * 300512)


WDR13 gene has been proposed as a candidate gene for X-linked intellectual disability. In 2021, Rzońca-Niewczas et al. were the first to describe a patient with an intellectual disability and a nonsense variant in WDR13 gene in depth and to study the effects of alterations in WDR13 gene in human cells. Our goal is to identify further individuals with pathogenic WDR13 variants to better define its phenotypic spectrum.
