Atrial septal defect (ASD) is an incomplete septation of atria in human heart causing circulatory problems. Its frequency is estimated at one per 10 000. Actions of numerous genes have been linked to heart development. However, no single gene defect causing ASD has yet been identified. Incomplete heart septation similar to ASD was reported in transgenic(More)
Mutations in COL1A1 or COL1A2 genes lead to osteogenesis Imperfecta (OI) in humans. There are three possiblities to successfully treat OI including (1) gene therapy, (2) mesenchymal stem cell (MSC) therapy, or (3) a combination of both. The aim of this study was to develop a model for combined gene/cell OI therapy by targeting Col1a1 and Col1a2 genes with(More)
BACKGROUND Age-related decrease in bone marrow erythropoietic capacity is often accompanied by the telomere length shortening in peripheral white blood cells. However, limited and conflicting data hamper the conclusive opinion regarding this relationship. Therefore, the aim of this study was to assess an association between telomere length and peripheral(More)
Fragile X syndrome (FXS) is the most common form of familial mental retardation and one of the leading known causes of autism. The mutation responsible for FXS is a large expansion of the CGG repeats in the promoter region of the FMR1 gene resulting in the transcriptional silencing of the gene in the pathophysiology of Fragile X syndrome was hypothesized.(More)
Fragile X syndrome (FXS) is the most common form of familial mental retardation and one of the leading known causes of autism. The mutation responsible for FXS is a large expansion of the CGG repeats in the promoter region of the FMR1 gene, resulting in the transcriptional silencing of the gene. Leptin may be considered a cytokine-like hormone with(More)
BACKGROUND Fragile X syndrome (FXS) is a single-gene disorder with a broad spectrum of involvement, including cognitive and behavioural impairments of varying degrees with specific physical features and a strong association with autism. OBJECTIVES In this study, the frequency of serum anti-neural antibodies was investigated in FXS patients who did and(More)
Characteristic, clinical features, typical for Wolf-Hirschhorn syndrome (WHS) were presented in the article. It is caused by partial deletion of the short arm of chromosome 4. The authors paid special attention to cytogenetic and molecular diagnostics of WHS. We mentioned some information concerning the search for the genes responsible for WHS features.(More)
