description | X-linked intellectual disability (XLID) is a clinically and genetically heterogeneous group of hereditary diseases caused by mutations on the X chromosome, which lead to impaired intellectual development. The paper determines for the first time the proportion of X-linked diseases (6.54%) in the pattern of intellectual disability in children. A system has been developed to quantify the clinical severity of fragile X mental retardation syndrome and Rett syndrome. A system has been scientifically justified to predict the clinical severity, which is based on an analysis of the impact of genetic and epigenetic factors (mutation type and location, X chromosome inactivation). The authors have determined the contribution of nonrandom X inactivation to the clinical polymorphism of various forms of XLID and established its role as an important diagnostic marker for pathology. It is shown that the study of X chromosome inactivation can identify asymptomatic female carriers of X-linked mutations to provide medical genetic counseling to families. An algorithm has been elaborated to diagnose XLID among the undifferentiated forms of mental developmental abnormalities in children. |
