Curry-Jones syndrome is a form of syndromic craniosynostosis, characterized by unilateral coronal craniosynostosis or multiple suture synostosis associated with complete or partial agenesis of the corpus callosum, preaxial polysyndactyly and syndactyly of hands and/or feet, along with anomalies of the skin (characteristic pearly white areas that become scarred and atrophic, abnormal hair growth around the eyes and/or cheeks, and on the limbs), eyes (iris colobomas, microphthalmia,) and intestine (congenital short gut, malrotation, dysmotility, chronic constipation, bleeding and myofibromas). Developmental delay and variable degrees of intellectual disability may also be observed. Multiple intra-abdominal smooth muscle hamartomas, trichoblastoma of the skin, occipital meningoceles and development of desmoplastic medulloblastoma have been reported.
Features include very common findings: 2-3 finger osseus syndactyly, Global developmental delay, Hypertelorism, and Hypopigmented skin patches and others; and common findings: Agenesis of corpus callosum, Unicoronal synostosis, Chronic constipation, and Duplication of thumb phalanx and others. 43 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Arms and legs | 7 | Preaxial hand polydactyly, Preaxial foot polydactyly, 2-3 finger osseus syndactyly |
SMO function has not been fully characterized.
Curry-Jones syndrome is associated with mutations in the SMO gene on chromosome 7.
Genetic testing for SMO is available. Testing is considered confirmatory for diagnosis.
Biomarker and diagnostic research for Curry-Jones syndrome has been reported in the published literature.
Phenotype severity distribution: 5 very common features, 18 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
No clinical trials have been registered for Curry-Jones syndrome.
104 publications have been identified in PubMed for Curry-Jones syndrome. Kisho has analyzed 31 by research type. Research spans Basic Science / Preclinical (42%), Case Report / Case Series (23%), and Review / Meta-Analysis (16%).
