OSBPL9 and arthrogryposis: Herein, we report a consanguineous family with fetal cerebral ventriculomegaly, cerebellar hypoplasia, and arthrogryposis multiplex associated with a homozygous novel nonsense mutation in the OSBPL9 gene. This is the first known report of a homozygous variant in the OSBPL9 gene in a recessive inheritance pattern and the first report of association with a fetal anomaly phenotype, to the best of our knowledge.
