| Lysosomal Storage Disorder v1.18 | SIDT2 |
Zornitza Stark gene: SIDT2 was added gene: SIDT2 was added to Lysosomal Storage Disorder. Sources: Literature Mode of inheritance for gene: SIDT2 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: SIDT2 were set to 40541391 Phenotypes for gene: SIDT2 were set to Lysosomal storage disease, MONDO:0002561, SIDT2-related Review for gene: SIDT2 was set to AMBER Added comment: Encodes a lysosomal membrane protein involved in trafficking of RNA into the lysosome for degradation via RNAutophagy. 1 affected individual described in PMID: 40541391 with two variants in SIDT2 presenting with progressive neurological decline in childhood with poor coordination, dysarthria, ataxia, cerebellar atrophy and cognitive decline. One variant confirmed to be maternally inherited, the other inheritance was unknown due to lack of availability of family members (as such phase not confirmed). Variants were c.1586G>A (?listed as p.Arg529Trp however protein consequence should be p.Arg529Gln) and c.2032C>T|p.Arg678Trp. Functional studies of patient fibroblasts showed markers of autophagy impairment and mouse models with reduced expression of SIDT2 had signs of progressive incoordination. LOF proposed mechanism. Supportive mouse model Sources: Literature |

| Lysosomal Storage Disorder v1.2 | ARSK |
Paul De Fazio gene: ARSK was added gene: ARSK was added to Lysosomal Storage Disorder. 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 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 |

| Lysosomal Storage Disorder v1.1 | CLCN7 |
Zornitza Stark gene: CLCN7 was added gene: CLCN7 was added to Lysosomal Storage Disorder. Sources: Literature Mode of inheritance for gene: CLCN7 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: CLCN7 were set to 31155284 Phenotypes for gene: CLCN7 were set to Hypopigmentation, organomegaly, and delayed myelination and development, MIM# 618541 Mode of pathogenicity for gene: CLCN7 was set to Loss-of-function variants (as defined in pop up message) DO NOT cause this phenotype - please provide details in the comments Review for gene: CLCN7 was set to AMBER Added comment: Two individuals reported with same missense variant and hypopigmentation, organomegaly, and delayed myelination and development. Variant is GoF. No osteopetrosis, biopsy findings from skin and other organs are consistent with a lysosomal storage disorder. IUGR, prematurity and polyhydramnios are features. Bi-allelic variants in this gene are associated with osteopetrosis. Sources: Literature |

| Lysosomal Storage Disorder v0.180 | TPP1 |
Zornitza Stark changed review comment from: Over 300 families reported, mutational spectrum reviewed in PMID 31283065. Two known pathogenic variants, c.509-1 G>C and c.622 C>T (p.(Arg208*)), collectively occurred in 60% of affected individuals in the sample, and accounted for 50% of disease-associated alleles.; to: Over 300 families reported, mutational spectrum reviewed in PMID 31283065.
