How is Wagner syndrome inherited?

How is Wagner syndrome inherited?

Wagner syndrome is inherited in an autosomal dominant pattern. It is caused by mutations in the VCAN gene encoding the proteoglycan versican.

What is Wagner Stickler syndrome?

Wagner syndrome is a rare progressive genetic disorder characterized by mild nearsightedness (myopia), degeneration of the thick, jelly-like fluid (vitreous) that fills the center of the eyes and the thin layer of nerve cells (retina) that lines the back of the eye (vitreoretinal degeneration), and distinctive facial …

Is Stickler syndrome dominant or recessive?

Stickler syndrome can be inherited in an autosomal dominant manner or in an autosomal recessive manner depending on the gene that has a change ( mutation or pathogenic variant). When Stickler syndrome is caused by pathogenic variants in COL2A1, COL11A1, or COL11A2, it is inherited in an autosomal dominant manner.

What are the different types of Stickler syndrome?

There are five types of Stickler syndrome: Stickler syndrome type I, Stickler syndrome type II, Stickler syndrome type III, Stickler syndrome type IV, and Stickler syndrome type V. Individuals with Stickler syndrome type I tend to have milder hearing loss, nearsightedness, and type 1 membranous vitreous anomaly.

It’s not contagious, and there’s no evidence that it’s inherited. The condition can lead to inflamed, narrowed blood vessels and harmful inflammatory tissue masses (granulomas).

What is PVR in ophthalmology?

Proliferative vitreoretinopathy (PVR), a major complication of rhegmatogenous retinal detachment (RRD), is an abnormal process whereby proliferative, contractile cellular membranes form in the vitreous and on both sides of the retina, resulting in tractional retinal detachment with fixed retinal folds.

What is the genotype for no freckles?

No freckles(observable) A genotypefor freckles is indicated by two alleles in one of the genes that causes freckles. The possible alleles using the first letter of the trait “f” are: F (dominant) = Has Freckles f (recessive) = No freckles
