Insertion-deletion polymorphisms (INDELs) are diallelic markers derived from a single mutation event. Their low mutation frequency makes them suitable for forensic and parentage testing. The examination of INDELs thus combines advantages of both short tandem repeats (STR) and single nucleotide polymorphisms (SNP). This type of polymorphisms may be examined(More)
An expanded polyglutamine stretch in the huntingtin protein has been identified as the pathogenetic cause of Huntington's disease (HD). Although the length of the expanded polyglutamine repeat is inversely correlated with the age-at-onset, additional genetic factors are thought to modify the variance in the disease onset. As linkage analysis suggested a(More)
The aim of the study was to analyze frequency of SHOX gene defects and selected dysmorphic signs in patients of both idiopathic short stature (ISS) and Léri-Weill dyschondrosteosis (LWD), all derived from the Czech population. Overall, 98 subjects were analyzed in the study. Inclusion criteria were the presence of short stature (-2.0 SD), in combination(More)
Germline mutations in the adenomatous polyposis gene (APC) result in familial adenomatous polyposis (FAP). FAP is an autosomal dominantly inherited disorder predisposing to colorectal cancer. Typical FAP is characterized by hundreds to thousands of colorectal adenomatous polyps and by several extracolonic manifestations. An attenuated form of polyposis(More)
Some of the APC negative FAP and AFAP cases have recently been found to be attributable to MYH associated polyposis (MAP). MAP is an autosomal recessive syndrome associated with 5-100 colorectal adenomas and caused by mutation in the MYH gene. Here, we screened for germline MYH mutations in 82 APC-mutation-negative probands with classical and attenuated(More)
BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is genetically heterogeneous and caused by mutations in at least three different loci. Based on linkage analysis, mutations in the PKD2 gene are responsible for approximately 15% of the cases. PKD2-linked ADPKD is supposed to be a milder form of the disease, its mean age of end-stage renal(More)
The expansion of a polymorphic CAG repeat in the HD gene encoding huntingtin has been identified as the major cause of Huntington’s disease (HD) and determines 42–73% of the variance in the age-at-onset of the disease. Polymorphisms in huntingtin interacting or associated genes are thought to modify the course of the disease. To identify genetic modifiers(More)
Familial adenomatous polyposis (FAP) is an autosomal dominant predisposition to colorectal cancer and is caused by germline mutations in the adenomatous polyposis coli gene. The most prominent clinical manifestation is the presence of hundreds to thousands of colorectal polyps. A milder phenotype is found in patients affected with AFAP/ multiple adenomas.(More)
ADPKD is the most common hereditary renal disease. IGAN is a mesangial proliferative glomerulonephritis characterized by diffuse mesangial deposition of immunoglobulin A. ET-1 has been suggested to be a major disease-promoting factor in renal diseases. The vasoconstrictor effect of ET-1 is mediated by the ET-A receptor. We have investigated the influence of(More)
Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome with almost 100 % risk of colorectal cancer. The typical FAP is characterized by hundreds to thousands of colorectal adenomatous polyps and by extracolonic manifestations, later onset and lower number of polyps in colon is characteristic of an attenuated form (AFAP). We analyzed the APC(More)
