The unifying pathognomonic sign is a cerebellar vermis hypoplasia presenting in MRI as the so called “molar tooth sign”. Approximately 25% of patients with JS present with NPH depending on the underlying genetic defect. [neocyst.de]

Summary Epidemiology Prevalence is estimated at approximately 1/100,000. Clinical description In the neonatal period, the disease often manifests by an irregular breathing pattern (episodic tachypnea and/or apnea), and nystagmus. [orpha.net]

The overall frequency of either p.R59H or 1622-1627insG was 57.7% of the disease-causing alleles, and this epidemiological study suggested a carrier frequency of 1:58 for this population 31. [centogene.com]

Epidemiology Although the incidence of JSRD has not been precisely determined, it may range between 1/80,000 and 1/100,000 live births, but may be underestimated [ 16, 17 ]. [ojrd.biomedcentral.com]
