INTRODUCTION The SHOX gene has been mapped at the pseudoautosomal region 1 (PAR1) of chromosomes X (Xp22.33) and Y (Yp11.32). The loss of SHOX gene functionality is assumed to be responsible for the Leri-Weill syndrome formation and the disproportionate short stature (DSS). The SHOX gene rearrangements constitute the majority of cases of gene functionality loss. Therefore, a practical applicati...
Microarray gene expression profiling is a high-throughput system used to identify differentially expressed genes and regulation patterns, and to discover new tumor markers. As the molecular pathogenesis of meningiomas and schwannomas, characterized by NF2 gene alterations, remains unclear and suitable molecular targets need to be identified, we used low density cDNA microarrays to establish exp...
The genetic predisposition Peutz-Jeghers Syndrome (PJS) has been shown to be associated with mutations in the serine threonine kinase 11 (STK11) gene but only a proportion of probands have been shown to harbour changes in the gene. The remaining patients were proposed to be either associated with a second PJS gene or they harboured more cryptic mutations within the STK11 gene itself. With the i...
Duchenne muscular dystrophy (DMD) is X-linked recessive neuromuscular disorders caused due to mutation in dystrophin gene, leading to progressive muscle weakness. This study was done to identify mutation in dystrophin gene in Nepalese patients with DMD using Multiplex Ligation Dependent Probe Amplification (MLPA) assay in Nepal. Twenty one patients from different regions of Nepal, who were clin...
The proximal region of the long arm of chromosome 15q11.2-q13 is associated with various neurodevelopmental disorders, including Prader-Willi (PWS) and Angelman (AS) syndromes, autism, and other developmental abnormalities resulting from deletions and duplications. In addition, this region encompasses imprinted genes that cause PWS or AS, depending on the parent-of-origin. This imprinting allow...
Killer immunoglobulin-like receptors (KIRs) are involved in the regulation of natural killer cell cytotoxicity. Within the human genome seventeen KIR genes are present, which all contain a large number of allelic variants. The high level of homology among KIR genes has hampered KIR genotyping in larger cohorts, and determination of gene copy number variation (CNV) has been difficult. We have de...
When rat dams consume a diet low in protein during pregnancy, their offspring develop high blood pressure. On a low-protein diet, the endogenous formation of the amino acid glycine is thought to become constrained. Glycine may become conditionally essential, as its rate of endogenous formation is inadequate to meet metabolic needs, and may be limiting for the normal development of the fetus. In...
PURPOSE To determine underlying correlations in multiplex ligation-dependent probe amplification (MLPA) data and their significance regarding survival following treatment of choroidal melanoma (CM). METHODS MLPA data were available for 31 loci across four chromosomes (1p, 3, 6, and 8) in tumor material obtained from 602 patients with CM treated at the Liverpool Ocular Oncology Center (LOOC) b...
Background and Aims: Congenital heart defects (CHD) are the most common type of congenital disability. Copy number variations (CNVs) have been found as one of the genetic etiology of non-syndromic CHD, and researchers have detected several pathogenic CNVs in patients with cardiac defects. Materials and Methods: In the present study, 70 patients with familial (20 patients) and sporadic (50 pati...
BACKGROUND Point mutations of the PRKAR1A gene are a genetic cause of Carney complex (CNC) and primary pigmented nodular adrenocortical disease (PPNAD), but in 30% of the patients no mutation is detected. OBJECTIVE Set up a routine-based technique for systematic detection of large deletions or duplications of this gene and functionally characterize these mutations. METHODS Multiplex ligatio...
