| Skeletal dysplasia v0.152 | ARSK |
Paul De Fazio gene: ARSK was added gene: ARSK was added to Skeletal dysplasia. Sources: Literature Mode of inheritance for gene: ARSK was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: ARSK were set to 34916232; 32856704 Phenotypes for gene: ARSK were set to Mucopolysaccharidosis MONDO:0019249, ARSK-related Review for gene: ARSK was set to GREEN gene: ARSK was marked as current diagnostic Added comment: 4 individuals from 2 unrelated consanguineous families reported with a homozygous missense and an NMD-predicted nonsense variant, who had features of mucopolysaccharidosis such as short stature, coarse facial features and dysostosis multiplex. Urinary GAG excretion was normal by conventional methods, but LC-MS/MS in 2 individuals revealed an increase in specific dermatan sulfate-derived disaccharides. Functional studies showed reduced protein levels and reduced enzyme activity for the nonsense and missense variant respectively. A mouse model also shows a mucopolysaccharidosis phenotype, albeit milder. Rated green (2 families, functional evidence, mouse model). Sources: Literature |
