background: precursor b-acute lymphoblastic leukemia (precursor b-all) oc-curs due to the uncontrolled proliferation of b-lymphoid precursors arrested at a par-ticular stage of b-cell development. precursor-b-all is classified mainly into pro-b-all, common-all and pre-b-all. the common acute lymphoblastic antigen cd10 is the marker for common-all. objective: this study was aimed to examine the ...
The need continues to grow for mutation identification in genetic disease in both research and clinical settings. We have developed a rapid nonradioactive bidirectional dideoxy fingerprint mutation screening procedure that is performed using an automated DNA analyzer. This technique features standardized primers and easily interpreted results from separate, but simultaneously collected, images ...
Neurofibromatosis type 1 is one of the most common inherited disorders with an incidence of 1 in 3000. The search for NF1 mutations has been hampered by the overall size of the gene, the large number of exons, and the high mutation rate. To date, fewer than 90 mutations have been reported to the NF1 mutation analysis consortium and the details on 76 mutations have been published. We have identi...
The myelin protein zero gene (MPZ) coding for the most abundant protein of the peripheral myelin was shown to be mutated in Charcot-Marie-Tooth type 1B disease (CMT1B). Later on MPZ mutations have been shown in axonal type of CMT (CMT2). Recently three novel MPZ gene mutations were reported in congenital hypomyelinating neuropathy (CHN). In contrast to the previously reported studies, focused o...
The aim of our study was to define mutations causing familial hypercholesterolemia (FH) phenotype in Czech hypercholesterolemic individuals. A combination of heteroduplex analysis, SSCP, DGGE, DNA sequencing and PCR/restriction analysis was used for this purpose. Molecular searching in the promoter region and coding sequence of the low density lipoprotein receptor (LDLR) gene in 130 patients fr...
The newly described heterotrophic estuarine dinoflagellate Pfiesteria piscicida has been linked with fish kills in field and laboratory settings, and with a novel clinical syndrome of impaired cognition and memory disturbance among humans after presumptive toxin exposure. As a result, there is a pressing need to better characterize the organism and these associations. Advances in Pfiesteria res...
A novel mutation at codon 441 in exon 10 of the adenomatous polyposis coli (APC) gene was identified in a South African family of mixed ancestry, using a convenient, non-radioactive, heteroduplex-SSCP screening assay. This single thymidine deletion after nucleotide position 1322 creates a frameshift resulting in a downstream stop codon at amino acid residue 453 of the APC gene. Genotypes of nin...
Hearing loss (HL) is the most frequent sensory defect affecting 1 in 1000 neonates. This can occur due to genetic or environmental causes or both. The genetic causes are very heterogenous and over 100 loci have been identified to cause autosomal recessive non - syndromic hearing loss (ARNSHL). The aim of this study was to determine the contribution of the LRTOMT gene mutations in causing ARNSHL...
PURPOSE Screening for mutations in the entire Cystic Fibrosis gene (CFTR) of Brazilian infertile men with congenital absence of vas deferens, in order to prevent transmission of CFTR mutations to offspring with the use of assisted reproductive technologies. METHOD Specific polymerase chain reaction (PCR) primers were designed to each of the 27 exons and splicing sites of interest followed by ...
