Intellectual disability syndromic and non-syndromic v0.2750 CCDC174 Konstantinos Varvagiannis gene: CCDC174 was added
gene: CCDC174 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature
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
Penetrance for gene: CCDC174 were set to Complete
Mode of pathogenicity for gene: CCDC174 was set to Other
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.
