Associated with phenotype in OMIM,but not in G2P.

PMID: 30624672 (2019) - 6-year-old girl with severe global developmental delay, pontocerebellar abnormalities, microcephaly, hypotonia, epilepsy and several systemic and peripheral dysfunctions. Exome sequencing revealed compound heterozygous variants in VPS51 ([c.2232delC; p.Asp745Thrfs*93];[c.1468C>T; p.Arg490Cys]). Functional studies of both variants indicate impaired function of the mutant protein.

PMID: 31207318 (2019) - two sisters with a homozygous three bp in-frame deletion (c.1419_1421del; p.Phe474del) in VPS51 associated with developmental delay, absent speech, severe ID and microcephaly. Development in both sisters was initially unremarkable; however, following an episode of fever (at 1 and 12 months of age, respectively), pyschomotor development was severely delayed. At 30 months and 9 years of age, respectively, neither sister had any language. No functional studies of the variant or patient cells were undertaken.

I don't know

Two families reported with bi-allelic variants in this gene and global developmental delay, impaired intellectual development with absent speech, microcephaly, and progressive atrophy of the cerebellar vermis and brainstem. Additional features, including seizures and visual impairment, are variable.
