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).
