Stickler Syndrome Precision Panel
Stickler Syndrome (SS), also known as hereditary arthroophthalmopathy belongs to the group of connective tissue disorders together with Marshall syndrome, and so have overlapping characteristics.
Overview
Stickler Syndrome (SS), also known as hereditary arthroophthalmopathy belongs to the group of connective tissue disorders together with Marshall syndrome, and so have overlapping characteristics. It is caused by mutations of genes in charge of the assembly of collagen. Since collagen is a major component of cartilage, vitreous and nucleus pulposus the clinical manifestations will affect these structures. Affected individuals are at significantly increased risk for retinal detachment and blindness, and early detection and diagnosis are critical in improving visual outcomes of these patients. The mode of inheritance varies from autosomal dominant, recessive and X-linked.
The Igenomix Stickler Syndrome Precision Panel can be used to make a directed and accurate diagnosis ultimately leading to a better management and prognosis of the disease. It provides a comprehensive analysis of the genes involved in this disease using next-generation sequencing (NGS) to fully understand the spectrum of relevant genes involved.
Indication
- The Igenomix Stickler Syndrome Precision Panel is indicated for those patients with a clinical diagnosis or suspicion with or without the following manifestations:
- Orofacial abnormalities: midfacial underdevelopment and cleft palate
- Ophthalmologic abnormalities: myopia, cataract, retinal detachment
- Hearing loss
- Precocious arthritis
Clinical Utility
The clinical utility of this panel is:
- The genetic and molecular confirmation for an accurate clinical diagnosis of a symptomatic patient.
- Early initiation of treatment with a multidisciplinary team in the form of surgical repair of orofacial abnormalities, retinal detachment, hearing and visual aids and symptomatic medical treatment for arthropathy. Early and continuous ophthalmologic examination follow-up to prevent further complications.
- Risk assessment of asymptomatic family members according to the mode of inheritance.
- Improvement of delineation of genotype-phenotype correlation.
