| Mendeliome v1.2400 | SVBP | Zornitza Stark edited their review of gene: SVBP: Added comment: PMID 39412222: 6 individuals from 3 families with spastic paraplegia and the same homozygous missense (L49P). Presented from birth or childhood with DD/ID and spastic paraplegia. Additional features: verbal apraxia, axonal neuropathy, ataxia, nystagmus, epilepsy, and aggressive behaviour. Brain MRIs were performed in 3 individuals and showed thinning of the corpus callosum, cerebellar atrophy, and ventriculomegaly; frontal ventricular hyperintensities suggestive of the 'ear of the lynx' sign in 2. Three individuals had a history of cancer of epithelial origin, including adenocarcinoma (patient 1), colonic tubular adenoma (patient 2), and breast cancer (patient 3).; Changed publications: 31363758, 30607023, 39412222; Changed phenotypes: Neurodevelopmental disorder with ataxia, hypotonia, and microcephaly, MIM #618569, Spastic paraplegia 94, autosomal recessive, MIM# 621150 | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Zornitza Stark changed review comment from: 5 unrelated families with homozygous mutations in SVBP. The mutations segregated with the disorder in all families. In vitro functional cellular expression studies showed that protein levels of the SVBP mutants were barely detectable, suggesting instability, and that the mutant proteins had lost VASH/SVBP catalytic detyrosination activity toward tubulin. Knockdown of about 50% Svbp expression using shRNA in rat hippocampal neurons impaired the formation of excitatory synapses compared to controls. Sources: Literature; to: 5 unrelated families with homozygous mutations in SVBP. Some shared the same founder variant, p.Q28*. The mutations segregated with the disorder in all families. In vitro functional cellular expression studies showed that protein levels of the SVBP mutants were barely detectable, suggesting instability, and that the mutant proteins had lost VASH/SVBP catalytic detyrosination activity toward tubulin. Knockdown of about 50% Svbp expression using shRNA in rat hippocampal neurons impaired the formation of excitatory synapses compared to controls. Sources: Literature |
