Abstract

The human proteins rabenosyn-5 and VPS45 form a complex that plays a key role in early endocytosis. Pathogenic variants in VPS45 cause severe congenital neutropenia (SCN) with impaired neutrophil function, reticulin fibrosis of the bone marrow, and extramedullary hematopoiesis (OMIM: 615285). Patients with a specific VPS45 variant (p.Glu238Lys) also have intellectual disability and bilateral optic nerve hypoplasia. To date, the only evidence of a potential role for RBSN in human disease is the report of a homozygous missense variant (p.Gly425Arg) in a patient with intellectual disability, seizures, microcephaly, osteopenia, mild reticulin fibrosis of the bone marrow, and transient neutropenia.
