XPO7-associated neurodevelopmental disorder

Targeted gene(s)/phenotype under study :

  • Gene: XPO7 (OMIM # 606140 )

Abstract :

XPO7 encodes for exportin 7 or RAN-Binding Protein 16, a member of the importin-beta superfamily of nuclear transport receptors and implicated in the nuclear transport of proteins. Exportin 7 is highly expressed in brain but not yet reported in human pathology. We have collected 8 patients from different countries with (de novo) XPO7 variants and neurodevelopmental disorders. The phenotype is broad (developmental delay, intellectual disability, dysmorphic features, seizures, microcephaly) but patients share similarities and interestingly, four patients have the same missense variant.

We would like to constitute a cohort of patients with XPO7 variants in order to delineate the phenotype of this rare disease and are currently planning functional validation of pathogenicity of the variants.
