Case report of the first molecular diagnosis of Stickler syndrome with a pathogenic COL2A1 variant in a Mongolia family.

ABSTRACT:

Background

Stickler syndrome is a group of connective tissue disorders that can affect eye (myopia, cataract, and retinal detachment), skeleton (spondyloepiphyseal dysplasia and precocious arthritis), craniofacies (midfacial under development and cleft palate), and inner ear (conductive and sensorineural); with the degree of symptoms varying among patients. Mutations in the COL2A1, COL11A1, COL11A2, COL9A1, COL9A2, and COL9A3 procollagen genes cause Stickler syndrome.

Case presentation

A 16-year-old Mongolian girl approached our clinics with retinal detachment. The proband had vitreous degeneration in both eyes, rhegmatogenous retinal detachment in her right eye, a large area of retina degeneration in her left eye, and coupled with severe myopia. No obvious hearing disorder
