Opis:
Introduction and aim. Mutation(s) in the gene encoding the CD19 molecule affect CD19 protein expression and primary immunodeficiency (PID) occurs. The PCR-RFLP method, which is faster and cheaper than other mutation detection methods, is rarely used in the diagnosis of PID. The study aimed to genetically identify CD19 deficiency, which is a PID, using the PCR-RFLP method. Material and methods. A total of 8 patients and two healthy controls were included in the study and the relevant region genotypes in the CD19 gene were determined by performing PCR-RFLP analysis. Results. The index case, newborn baby and mother were also included in the study. It was determined that the index case (P6) was homozygous mutant, the newborn baby (P7) and mother (P8) had heterozygous genotype. Based on this situation, one child (P1) was found to be homozygous mutant, mother (P2), father (P3) and other children (P4 and P5) had heterozygous genotype in the family, which was determined to be related to the first case. Conclusion. In our study, it has been shown that PCR-RFLP is a method that can be used in the diagnosis of PID by determining genotypes using PCR-RFLP, and especially in terms of rapid genetic testing of family screenings.

Opis:
The goal of work was identification A1 variant of bovine beta casein which involves ischemic heart disease and diabetes mellitus in human. The digestion of A1beta casein can result in the production of bioactive beta casomorphin-7 (BCM-7); this is not the case with A2. This bioactive peptide has been linked to physiological traits that may elicit effects on components of the vascular and immune systems. The material involved 111 Slovak Spotted breed. Bovine genomic DNA was extracted from whole blood by using commercial kit, and used in order to estimate beta-casein genotypes by means of PCR-RFLP method. The PCR products were digested with DdeI restriction enzyme. In the population included in the study were detected all three genotypes, homozygote genotype A1A1 (14 animals), heterozygote genotype A1A2 (37 animals) and homozygote genotype A2A2 (60 animals). In the total population of cattle homozygotes A2A2-0.5405 were the most frequent, while homozygotes A1A1-0.1261 were the least frequent ones. This suggests a superiority of allele A2 (0.7072) which does not produce BCM-7, and thus is safe for human consumption. The expected homozygosity for gene CSN2 is in the population stated a slight increase in homozygosity (0.5858). This caused a slight decrease in the level of possible variability realization (41.80%), which corresponds to the effective number of alleles (1.7071).

Opis:
The breast cancer suppressor proteins BRCA1 and BRCA2 interact with RAD51, a protein essential for maintaining genomic stability by playing a central role in homology-dependent recombinational repair of the DNA double-strand breaks. Therefore, genetic variability in the RAD51 gene may contribute to the appearance and/or progression of breast cancer. A single nucleotide polymorphism in the 5'- untranslated region of RAD51 (a G to C substitution at position 135, the G/C polymorphism) is reported to modulate breast cancer risk. We investigated the distribution of genotypes and frequency of alleles of the G/C polymorphism in breast cancer. Tumor tissues were obtained from postmenopausal women with node-negative and node-positive breast carcinoma with uniform tumor size. Blood samples from age matched healthy women served as control. The G/C polymorphism was determined by PCR-based MvaI restriction fragment length polymorphism. The distribution of the genotypes of the G/C polymorphism did not differ significantly (P >0.05) from those predicted by the Hardy-Weinberg distribution. There were no differences in the genotype distribution and allele frequencies between node-positive and node-negative patients. There were no significant differences between distributions of the genotypes in subgroups assigned to histological grades according to Scarf-Bloom-Richardson criteria and the distribution predicted by Hardy-Weinberg equilibrium (P >0.05). Our study implies that the G/C polymorphism of the RAD51 gene may not be directly involved in the development and/or progression of breast cancer and so it may not be useful as an independent marker in this disease.

Opis:
Polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) is a technique used to identify single nucleotide polymorphisms (SNPs) based on the recognition of restriction sites by restriction enzymes. RFLP-PCR is an easy-to-perform and inexpensive tool for initial analysis of SNPs potentially associated with some monogenic diseases, as well as in genotyping, genetic mapping, lineage screening, forensics and ancient DNA analysis. The RFLP-PCR method employs four steps: (1) isolation of genetic material and PCR; (2) restriction digestion of amplicons; (3) electrophoresis of digested fragments; and (4) visualisation. Despite its obsolescence and the presence of high-throughput DNA analysis techniques, it is still applied in the analysis of SNPs associated with disease entities and in the analysis of genetic variation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). RFLP-PCR is a low-cost and low-throughput research method allowing for the analysis of SNPs in the absence of specialised equipment, and it is useful when there is a limited budget.

Opis:
Postęp, jaki nastąpił w biologii molekularnej poprzez wprowadzenie markerów molekularnych nowej generacji, w ciągu ostatnich 20 lat umożliwił znaczny rozwój wielu dziedzin badań. Możliwe stało się uzyskanie dokładniejszych informacji genetycznych pozwalających na lepsze zrozumienie zasobów genetycznych organizmów. Markerem molekularnym może być każda sekwencja nukleotydowa (wybrany fragment DNA), rozproszony w całym genomie, której zmienność między osobnikami lub grupami taksonomicznymi umożliwia precyzyjną identyfikację osobnika/taksonu. Kompilacja właściwości enzymów restrykcyjnych jak również reakcji łańcuchowej polimerazy (PCR) w technikach generujących markery molekularne pozwoliła na efektywne wykorzystanie ich w taksonomicznych, ewolucyjnych i ekologicznych badaniach roślin.
Over the last 20 years, the progress in molecular biology through the introduction of new generation molecular markers has allowed many areas to move forward. It has now become possible to obtain more accurate genetic information to better understand the genetic resources of organisms. A molecular marker can be any nucleotide sequence (selected DNA fragment) scattered throughout the genome, whose variability between individuals or taxonomic groups allows precise identification of the individual/taxon. The effectiveness of restriction digestion and polymerase chain reaction based on molecular markers has already proved their usefulness in taxonomic, evolutionary and ecological plant research.

Opis:
The MTHFR gene within the human genome, codes for the synthesis of Methylenetetrahydrofolate Reductase enzyme, which reduces 5,10-Methylenetetrahydrofolate to 5-Methyltetrahydrofolate, which in turn, is the major circulatory form of folate in the blood. Folate, in this form, among it’s other functions, is involved in reducing the homocysteine levels in the blood, whose elevated levels lead to Hyperhomocysteinemia, causing various major disorders. Mutations within the gene lead to impairment of gene function, in turn causing the homocysteine levels to rise. The C677T and A1298C mutations are the main causative agents for MTHFR gene disruption. During the course of the project, a total of 79 samples were analyzed for the presence of these mutations. The blood samples were first subjected to PCR, giving two separate DNA fragments each responsible for either of the conditions. The fragments were then subjected to RFLP analysis to detect the mutations. The results were finally given with respect to the risk factor faced by each individual based on a molecular diagnostic point of view.

Opis:
Despite of the growing interest in pike-perch for aquaculture and its economic importance in fisheries, knowledge on the population structure and phylogeography of the species is still limited. We report the discovery of two major cytochrome b lineages and describe a simple method for their detection based on PCR amplification followed by restriction digestion with Alw26I. Screening of 708 individuals showed that haplotype A was fixed or dominating in Central and East European countries, whereas haplotype B was mainly found in several French populations and Tunisian pike-perch introduced from Europe. Sequencing the complete cytochrome b cds of 17 representative individuals revealed that haplotypes A and B differed by five substitutions but also showed further differentiation of both haplotypes due to an additional substitution in a single haplotype A and B individual from France, respectively. Five partial pike-perch cytochrome b cds available from NCBI GenBank could also clearly be assigned to one or the other of the two major lineages. Therefore, this new mtDNA marker might be considered as suitable not only for studies on population structure and phylogeography of pikeperch but also to trace its introduction history and to assess the genetic composition of aquaculture brood stocks.

The ubiquitin-conjugating enzyme E2E 2 (UBE2E2) gene plays an important role in insulin synthesis and secretion under conditions in which stress to the endoplasmic reticulum is increased in β-cells. In this case-control study, we have selected rs7612462 polymorphism within UBE2E2 gene to identify in a Saudi population the type 2 diabetes mellitus (T2DM) subjects. In total, 376 subjects with T2DM and 380 controls were enrolled in this study. We have collected 5 mL of peripheral blood from each participant for biochemical and molecular analyses. PCR-RFLP was used to generate genotypes at rs7612462 in all of the study subjects. Clinical data and anthropometric measurements of the patients were significantly different from those of the controls (p<0.05). All of the subjects used in this study were non-obese (25

Opis:
The diagnosis of fungal infections remains a problem for the management of fungal diseases, particularly in the immunocompromised patients. Systemic Candida infections and invasive aspergillosis can be a serious problem for individuals who need intensive care. Traditional methods used for the identification and typing of medically important fungi, such as morphological and biochemical analysis, are time−consuming. For the diagnosis of mycoses caused by pathogenic fungi faster and more specific methods, especially after the dramatic increase in nosocomial invasive mycoses are needed. New diagnostic tools to detect circulating fungal antigens in biological fluids and PCR−based methods to detect species or genus−specific DNA or RNA have been developed. Antigen detection is limited to searching only one genus. Molecular genetic methods, especially PCR analysis, are becoming increasingly important as a part of diagnostics in the clinical mycology laboratory. Various modifications of the PCR method are used to detect DNA in clinical material, particularly multiple, nested and real−time PCR. Molecular methods may be used to detection of nucleic acids of fungi in clinical samples, to identify fungal cultures at the species level or to evaluate strain heterogeneity differences within the species. This article reviews some of the recent advances in the possibility of molecular diagnosis of fungal infections.
