While phenotypic findings may differ among patients, it may appear normal in the neonatal period, as facial features are not evident. The first clinical signs include nutritional difficulties, hypotonia, microcephaly, neuromotor developmental retardation and joint hypermobility. Due to neutropenia, upper respiratory infections and oral aphthae could be observed. The disease has an autosomal recessive inheritance pattern and is caused by mutations in the VPS13B gene.eninfo:eu-repo/semantics/closedAccessOther28SUPPL 1911911WOS:000598482603238Q2
