Intellectual disability - microarray and sequencing v3.283 | CCDC174 |
Arina Puzriakova Added comment: Comment on list classification: Rating Red as only one founder variant reported to-date in a single publication - currently no evidence that other variants in this gene are disease-causing. Added 'founder-effect' tag |

Konstantinos Varvagiannis gene: CCDC174 was added gene: CCDC174 was added to Intellectual disability. 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.
