Rett syndrome (RTT), an X-linked dominant neurodevelopmental disorder in females, is caused mainly by de novo mutations in the methyl-CpG-binding protein 2 gene (MECP2). Here we report mutation analysis of the MECP2 gene in 87 patients with RTT from the Czech and Slovak Republics, and Ukraine. The patients, all girls, with classical RTT were investigated(More)
OBJECTIVE Digenic causes of human disease are rarely reported. Insulin via its receptor, which is encoded by INSR, plays a key role in both metabolic and growth signaling pathways. Heterozygous INSR mutations are the most common cause of monogenic insulin resistance. However, growth retardation is only reported with homozygous or compound heterozygous(More)
OBJECTIVE—Inactivating mutations in glucokinase (GCK) cause mild fasting hyperglycemia. Identification of a GCK mutation has implications for treatment and prognosis; therefore, it is important to identify these individuals. A significant number of patients have a phenotype suggesting a defect in glucokinase but no abnormality of GCK. We hypothesized that(More)
Mental retardation (MR) is a frequent manifestation in patients referred to departments of medical genetics (OLG). At the OLG in Martin their number in the years 1981-1985 was 324, i.e. 21.22% of the total number of examined subjects. MR was found as one of the pathological symptoms (symptomatic MR) in 86.73% and as the only pathological manifestation(More)
Inheritance and expression of mitochondrial DNA (mtDNA) mutations are crucial for the pathogenesis of Leber hereditary optic neuropathy (LHON). We have investigated the segregation and functional consequences of G3460A mtDNA mutation in 27 members of a three-generation family with LHON syndrome. Specific activity of respiratory chain complex I in platelets(More)
