A genetic study of children attending ESN(M) schools in Coventry has shown a recurrence risk of idiopathic mental retardation in sibs lying between 1 in 4 and 1 in 5. There was also a prevalence of mental retardation in other relatives that was greater than the population prevalence, and was less for second degree relatives than for first degree, and less still for third degree relatives. Recur...
background adaptation is an important process for humans. children, who are physically or mentally disabled, impose special stresses on their families, parents and in particular on their mothers. objectives this study examines the relationship between the characteristics of mothers who have educable mentally retarded children, and their adaptation based on roy’s adaptation model. patients and m...
Subtelomeric rearrangements are believed to be responsible for 5-7% of idiopathic mental retardation cases. Due to the relative complexity and high cost of the screening methods used till now, only preselected patient populations including mostly the more severely affected cases have been screened. Recently, multiplex ligation-dependent probe amplification (MLPA) has been adapted for use in sub...
This paper describes a community based study of 156 boys with idiopathic, severe mental retardation. The boys were examined and a pedigree taken before the cytogenetic results were known. The prevalence of the fragile X chromosome among this group of boys was high: 9% in the whole group and 11% after 39 boys with specific features had been excluded. The fragile X syndrome is therefore an import...
Cryptic subtelomeric chromosome anomalies have been recognized as a significant cause of dysmorphology and mental retardation. To determine whether the clinical cytogenetics laboratory should screen routinely for these aberrations, we have tested 250 patients with idiopathic mental retardation/developmental delay, either isolated (53) or associated with dysmorphic features and/or malformations ...
