Presentation
Depression or prominence of the chest bone may be present. Face: Children with Stickler Syndrome present with characteristic facial features like flat cheekbones, flat nose, long upper lip and small chin. [medindia.net]
At presentation, 22 (31.4%) eyes had a giant tear, six (8.6%) eyes had a horseshoe break, single breaks were present in seven (10.0%) eyes, multiple breaks in 35 (50%) eyes, and macular hole in two (2.85%) eyes. [dovepress.com]
Varied clinical presentations have been found, probably due to the different type of collagens found in different part of the body, but only this solely cannot explain the phenotypic distinction. [jpgo.org]
Together the data from the present study and the previous studies suggest that loss-of-function mutations in any of the collagen IX genes can cause autosomal recessive Stickler syndrome. [ncbi.nlm.nih.gov]
However, midface hypoplasia and micrognathia may be present in all types as well as in Marshall syndrome. Midline clefting usually does not occur. [disorders.eyes.arizona.edu]

Amblyopia ; Astigmatism ; Cataract ; Cleft palate ; Epiphyseal dysplasia ; Flat face ; Genu valgum ; Irregular vertebral endplates ; Joint hyperflexibility ; Malar flattening ; Micrognathia ; Myopia ; Platyspondyly ; Retinal detachment ; Sensorineural hearing [beta.mousephenotype.org]
Pierre Robin sequence, hearing impairment/loss and joint hypermobility are common. Eye manifestations include high myopia, cataract, retinal detachment, and vitreous abnormalities. [egl-eurofins.com]
Hearing impairment is common in STK-affected individuals and it can be of variable degree and is commonly progressive: Sensorineural hearing impairment with typically high-tone is diagnosed in 40% of individuals 1, 2 Overall sensorineural hearing loss [centogene.com]

However the most serious features of the syndrome can cause vision and hearing impairment, as well as problems with the joints. [fdna.health]
Workup
Due to the retrospective nature of our study, the lack of a genetic workup and family evaluation, we were unable to analyze the pattern of inheritance in the study cohort. [dovepress.com]
Treatment
Put the very latest scientific and genetic discoveries, diagnostic imaging methods, drug therapies, treatment recommendations, and surgical techniques to work in your practice. [books.google.com]
There is no cure for Stickler syndrome, but treatment is available for managing the symptoms. [innerbody.com]
Treatment Treatment Options: The myopia and hearing loss can be corrected. Lifelong vigilance and prompt treatment are required for the vitreoretinal disease. [disorders.eyes.arizona.edu]
Prognosis

What is the Prognosis of Stickler Syndrome? Stickler Syndrome does not affect the life expectancy of an individual. Once diagnosed, the doctor and the patient's parents can take proactive steps to monitor any abnormality and promptly correct it. [medindia.net]
Confirming a genetic diagnosis is essential to determine prognosis and establish a risk for recurrence. Aneuploidies such as Trisomy 13 and 18 have a strong association with CL/CP. [perioimplantadvisory.com]

Etiology and Pathogenesis Frequency This heterogeneous birth defect has a prevalence of approximately 1 per 8500 live births. The male-to-female ratio is 1:1, except in the X-linked form. Etiology Autosomal recessive inheritance is possible. [emedicine.medscape.com]
The likelihood of a genetic or teratogenic etiology increases the more congenital anomalies with which a patient presents. [perioimplantadvisory.com]

This finding will have a major impact on the genetic counseling of patients with Stickler syndrome and on the understanding of the pathophysiology of collagens. [scicrunch.org]
The exact pathophysiological mechanism is unclear; however it is most probably associated with the expression of type II and IX collagen in the inner ear 2, 4. [centogene.com]
Prevention
Prevention Stickler syndrome is an inherited condition and cannot be prevented. Genetic screening can help affected adults assess disease risk to their offspring. Early diagnosis and treatment is key to preventing serious complications. [innerbody.com]

As the therapy of choice to correct the conductive hearing loss and prevent middle ear complications, tympanostomy tubes are usually inserted when the palatoplasty is performed. [emedicine.medscape.com]
