Intellectual disability syndromic and non-syndromic v0.2762 CNPY3 Zornitza Stark Classified gene: CNPY3 as Green List (high evidence)
Intellectual disability syndromic and non-syndromic v0.2762 CNPY3 Zornitza Stark Gene: cnpy3 has been classified as Green List (High Evidence).
Intellectual disability syndromic and non-syndromic v0.2750 CNPY3 Konstantinos Varvagiannis gene: CNPY3 was added
gene: CNPY3 was added to Intellectual disability syndromic and non-syndromic. Sources: Literature
Mode of inheritance for gene: CNPY3 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: CNPY3 were set to 29394991; 30237576
Phenotypes for gene: CNPY3 were set to Epileptic encephalopathy, early infantile, 60 (MIM 617929)
Penetrance for gene: CNPY3 were set to Complete
Review for gene: CNPY3 was set to GREEN
Added comment: Biallelic CNPY3 mutations cause Epileptic encephalopathy, early infantile, 60 (MIM 617929).

The phenotype including among others hypotonia, intractable seizures, DD and ID has been first reported by Mutoh et al (2018 - PMID: 29394991) in 3 subjects from 2 families. Evidence was provided for the role of the gene (incl. mouse model) and pathogenicity of the identified variants (resulting in LoF).

Another subject with similar features of hypotonia, DD, intractable epilepsy, feeding problems has been described briefly by Maddirevula et al (2019 - PMID: 30237576).
