Genetic Types of Inheritance of Retinal Pigment Abiotrophy in Patients Living in “Closed” Communities in the Republic of Buryatia

| Sumario: | Retinal pigment abiotrophy is a hereditary disease with a primary diffuse lesion of photoreceptors and the retinal pigment epithelium, in which characteristic functional changes and a typical picture of the fundus with pigment bone bodies are noted. Retinal pigment abiotrophy is the most common disease of all dystrophies of the retina.Aim. To do a clinical genealogical analysis of the type of inheritance of pigmentary retinitis in residents of Tarbagatai region of the Republic of Buryatia.Material and methods. At the first stage of the study, a round between the residents of Tarbagatai region of the Republic of Buryatia was conducted by interviewing and questioning. At the second stage, people with suspected pigment retinitis and their blood relatives underwent a full ophthalmologic examination to confirm the diagnosis, and a thorough collection of genealogical information was carried out to determine the type of inheritance.Results. 20 patients were allocated from 12 families of 1237 interviewed people aged 15 to 76 years living in a closed community in the territory of Buryatia in the Tarbagatai region, 12 of them with a presumptive diagnosis of retinitis pigmentosa, with signs of Usher syndrome (retinitis pigmentosa + sensorineural hearing loss) – 8 people. In general, the analysis of 20 pedigrees with an established type of inheritance in 89.9 % of cases revealed an autosomal recessive type; in 10.1 % – autosomal dominant type of retinitis pigmentosa.Conclusion. A complete collection of genealogical history is the basis for the diagnosis of hereditary eye diseases. |
