BabyScreen+ newborn screening v0.1721 COL9A1 Zornitza Stark Gene: col9a1 has been classified as Green List (High Evidence).
BabyScreen+ newborn screening v0.1721 COL9A1 Zornitza Stark Tag treatable tag was added to gene: COL9A1.
Tag ophthalmological tag was added to gene: COL9A1.
BabyScreen+ newborn screening v0.1710 COL9A1 David Amor changed review comment from: Gene-disease association: strong but rare, prbably <1% of Sticller syndrome; Van Camp et al. (2006) described a consanguineous Moroccan family in which 4 of 10 sibs had features characteristic of Stickler syndrome, including moderate to severe sensorineural hearing loss, moderate to high myopia with vitreoretinopathy, and epiphyseal dysplasia. Nikopoulos et al. (2011) reported 2 sisters in a Turkish family and 1 boy in a Moroccan family with features of autosomal recessive Stickler syndrome. All 3 individuals had myopia, vitreous changes, sensorineural hearing loss, and epiphyseal dysplasia. They also had exudative rhegmatogenous retinal detachment.

Severity: moderate-severe

Age of onset: congenital

Non-molecular confirmatory testing: Affected individuals have moderate-to-severe sensorineural hearing loss, moderate-to-high myopia with vitreoretinopathy, cataracts, and epiphyseal dysplasia

Treatment: as per other Stickler syndrome; to: Gene-disease association: strong but rare, prbably <1% of Sticller syndrome; Van Camp et al.
