Mendeliome v0.10838 ARSK Zornitza Stark Marked gene: ARSK as ready
Mendeliome v0.10838 ARSK Zornitza Stark Gene: arsk has been classified as Green List (High Evidence).
Mendeliome v0.10838 ARSK Zornitza Stark Phenotypes for gene: ARSK were changed from Mucopolysaccharidosis to Mucopolysaccharidosis MONDO:0019249, ARSK-related
Mendeliome v0.10837 ARSK Zornitza Stark Classified gene: ARSK as Green List (high evidence)
Mendeliome v0.10837 ARSK Zornitza Stark Gene: arsk has been classified as Green List (High Evidence).
Mendeliome v0.10835 ARSK Paul De Fazio gene: ARSK was added
gene: ARSK was added to Mendeliome. 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 (Turkish and Indian) reported with a homozygous missense and an NMD-predicted nonsense variant. Affected individuals 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).

Mendeliome v0.8913 GH1 Zornitza Stark Phenotypes for gene: GH1 were changed from to Growth hormone deficiency, isolated, type IA, MIM# 262400; Growth hormone deficiency, isolated, type II, MIM# 173100; Kowarski syndrome, MIM# 262650
Mendeliome v0.8910 GH1 Zornitza Stark reviewed gene: GH1: Rating: GREEN; Mode of pathogenicity: None; Publications: 2840669, 1603635, 12655557, 15671105, 8552145, 9276733, 15713716; Phenotypes: Growth hormone deficiency, isolated, type IA, MIM# 262400, Growth hormone deficiency, isolated, type II, MIM# 173100, Kowarski syndrome, MIM# 262650; Mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal
Mendeliome v0.8897 FGD1 Zornitza Stark Phenotypes for gene: FGD1 were changed from to Aarskog-Scott syndrome, MIM # 305400; Mental retardation, X-linked syndromic 16, MIM# 305400
Mendeliome v0.8894 FGD1 Zornitza Stark reviewed gene: FGD1: Rating: GREEN; Mode of pathogenicity: None; Publications: 7954831, 20082460; Phenotypes: Aarskog-Scott syndrome, MIM # 305400, Mental retardation, X-linked syndromic 16, MIM# 305400; Mode of inheritance: X-LINKED: hemizygous mutation in males, biallelic mutations in females
Mendeliome v0.3321 CCDC174 Zornitza Stark gene: CCDC174 was added
gene: CCDC174 was added to Mendeliome. Sources: Expert Review
Mode of inheritance for gene: CCDC174 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: CCDC174 were set to 26358778
Phenotypes for gene: CCDC174 were set to Hypotonia, infantile, with psychomotor retardation - IHPMR, 616816
Review for gene: CCDC174 was set to AMBER
Added comment: Biallelic pathogenic CCDC174 variants cause Hypotonia, infantile, with psychomotor retardation - IHPMR (MIM 616816). Volodarsky et al [2015 - PMID: 26358778] describe 6 children from 2 unrelated families with - among others - severe hypotonia, psychomotor delay and abducens nerve palsy. All affected subjects were homozygous for a stoploss variant. Evidence from functional studies/animal model is provided supporting the role of the gene in this phenotype. Overall this gene can be considered for inclusion in the ID panel with amber rating (2 families, single founder variant, consistent phenotype, supportive studies) pending further reports.
