Variants in the ATL1 gene have been repeatedly described as the second most frequent cause of hereditary spastic paraplegia (HSP), a motor neuron disease manifested by progressive lower limb spasticity and weakness. Variants in ATL1 have been described mainly in patients with early onset HSP. We performed Sanger sequencing of all coding exons and adjacent intron regions of the ALT1 gene in 111 Czech patients with pure form of HSP and additional Multiplex-Ligation Probe Analysis (MLPA) testing targeting the ATL1 gene in 56 of them.

The CDKL5 protein is a kinase required for neuronal development and morphogenesis, but its precise functions are still largely unexplored. Individuals with CDKL5 mutations present with severe global developmental delay, intractable epilepsy, and Rett-like features.

Four percent of SMA patients have a combination of the deletion or conversion on one allele and an intragenic mutation on the second one. We performed analysis of point mutations in a set of our patients with suspicion of SMA and without homozygous deletion of the SMN1 gene.

Objectives: Glucose metabolism disorders usually coexist with dyslipidemia and coagulation/fibrinolysis disturbances. Increase of insulin resistance followed by hyperinsulinemia leads to enhanced protein synthesis, including production of apolipoproteins. As a result, the structure of Low Density Lipoprotein (LDL) becomes small and dense.

Background And Objective: Metabolic syndrome is characterized by insulin resistance (IR) as well as dyslipidemia, ventral overweight, hypertension and elevated fasting plasma glucose. Since diabetic and prediabetic states are commonly associated with hypertriglyceridemia, fenofibrates have been used in such patients. The aim of this pilot open trial was to study the influence of micronized fenofibrate on insulin resistance and plasma insulin levels in prediabetic and diabetic patients.
