Targeted gene/syndrome under study:

DPF2 (OMIM 601671), Coffin-Siris syndrome type 7 (OMIM 601671)


Coffin-Siris syndrome type 7 (CSS7) is a neurodevelopmental disorder caused by dominant negative variants in the PHD1 or PHD2 domain of the DPF2 gene. We were the first to identify affected individuals with mutations in DPF2. Patients showed borderline to moderate developmental delay/intellectual disability, muscular hypotonia, facial dysmorphism and ectodermal anomalies. We aim to further expand the mutational and clinical spectrum of CSS7 by reporting novel variants and systematically describing the clinical aspects according to the Human Phenotype Oncology. Furthermore, we are aiming to perform methylome analysis.
