Abstract
AIM To determine the frequency of NOD2 gene c.3019-3020insC (rs5743293) and c.2104C>T (rs2066844) allelic variants in the patients with Crohn's disease (CD), colorectal cancer (CRC) and in the control groups and to study the association of these mutations with the onset time of the diseases, gender and surgical interventions. MATERIALS AND METHODS The diagnoses of CD and CRC were established based on standard clinical examination and laboratory tests. Molecular genetic study of a frameshift 3020insC mutations of NOD2 gene were performed in 54 patients with CD; missense R702W mutations of the NOD2 gene - in 41 CD patients and 38 healthy controls. In CRC group, 3020insC mutation was tested in 48 patients, R702W mutation - in 40 patients and 40 healthy controls. PCR-RFLP technique was used to identify the mutations. RESULTS The frequency of the minor allele (M) of 3020insC mutation of NOD2 gene in the patients with CD was significantly higher than in the control group (р = 0.01). The age at CD onset in females carrying 3020insC mutation was significantly lower (22.5 ± 1.6 years) when compared with females without the mutation (32.7 ± 2.5 years) (p = 0.002). There was no significant difference in the allele frequencies and genotype distributions of R702W mutation in the patients with CD in comparison with the controls. The mean age at CD onset in the patients carrying R702W mutation was significantly lower (28.4 ± 1.4 years) compared with the patients without the mutation (39.4 ± 2.8 years) (p < 0.01). Surgical interventions for CD was required in 40.0% of 3020insC mutation carriers. Among patients with CRC, only 4.2% carried 3020insC mutation and 20.0% R702W mutation. Our study suggests that R702W and 3020insC mutations are not associated with the risk of CRC in Ukrainian patients. There was no statistically significant difference in mean age at CRC onset in patients with/without R702W mutation. Only one patient with CRC had two mutations. CONCLUSION The earlier age at CD onset was associated with 3020insC mutation, but only in female patients. The association between R702W mutation and the earlier age of CD onset was found. Patients with 3020insC mutation showed a trend to a higher frequency of surgical interventions for CD.

Abstract
AIM To study the relationship between the genotype and the phenotype in the patients with Hermansky - Pudlak syndrome (HPS) associated with granulomatous colitis; to monitor clinical course of the disease for adequate treatment, cancer surveillance and genetic counseling. MATERIALS AND METHODS The diagnosis of HPS is established by physical examination, chest X-ray, computed tomography, endoscopic examination with biopsy, and laboratory tests, including histology, baseline laboratory blood, urine and feces tests, determination of ASCA-C and ANCA antibodies using an ELISA. Molecular genetic testing for HPS gene mutations, R702W, G908R, L1007fs and P268S mutations in NOD2 gene, and TaqI variant of the VDR gene were carried out. RESULTS We report 2 cases of HPS from unrelated families. Both were complicated by inflammatory bowel disease with pathologic features of Crohn's disease refractory to antibiotics and corticosteroids. One patient (family 1) with Ashkenazi Jewish ancestry had pathogenic variant of the HPS-4 gene in exon 8, mutation P268S of NOD2 genes and "Tt" genotype of TaqI variant of the VDR gene. Another patient (family 2) carried two mutations P268S and G908R of NOD2 gene, and had a large paraovarian cyst diagnosed. No consistent success with the standard medical therapy, used for treating granulomatous colitis, associated with HPS, in presented cases was achieved. Patients needed surgical interventions at a young age and a long-term surveillance of the probable development of tumors and other complications. Azathioprine at 2 mg/kg/day and mesalazine 3 g/day were used with some positive effect for prevention of Crohn's disease postoperative recurrence. CONCLUSION The occurrence of perianal lesions, the histopathological findings and the results of the molecular genetic analysis confirmed the mutations P268S and G908R of NOD2 gene in these cases suggest that HPS was truly associated with Crohn's disease variant with early onset and severe course. The search for the molecular causes of the disease in some individuals may help in the development of new therapeutic and surgical approaches, as well in the improvement of understanding of premalignant inflammatory conditions in a large bowel.

Abstract
AIM To describe the case of metachronous gastrointestinal stromal tumors in a proband with familial adenomatous polyposis (FAP), carrier of APC gene mutation in codon 1309. MATERIAL AND METHODS The physical examination, genealogical analysis and molecular genetic analysis of peripheral blood in 15-years-old girl with FAP and her sister, were carried out. Macroscopic, standard histological and immunohistochemical study of surgical specimens - intraintestinal tumors of the small intestine in proband was performed. RESULTS Extraintestinal manifestations, including congenital abnormalities of facial skeleton, typical for Gardner's syndrome, were observed in the sisters with FAP as the addition symptoms of the disease. Frameshift mutation in codon 1309 in the APC gene was detected in these patients. A rare neoplasia - metachronous gastrointestinal stromal tumor was found in proband 15 months after total colectomy for FAP. This is the third case described in the accessible medical literature. CONCLUSION The possible role of APC gene mutation in the development of mesenchymal neoplasms is discussed. The study of stromal tumors is important for understanding of their pathogenesis that will enable to develop effective targeted therapy.

Abstract
INTRODUCTION Attenuated adenomatous polyposis coli (AAPC) is a variant of the familial adenomatous polyposis (FAP) characterized by the occurrence of sparse polyps in the colon, stomach, and duodenum with a late onset of colorectal cancer. The AAPC syndrome is associated with mutations at the 5' region of the APC gene. Until recently, the fragment encompassing codons 157 and 170 was considered as boundary for the described cases of AAPC and FAP syndromes. MATERIALS AND METHODS This study describes a case of the AAPC syndrome caused by a CCTT deletion at codon 173, with polyps diagnosed at the age of 17. The father and grandfather of the proband died of colorectal cancer (CRC), which developed from untreated polyps, at the age 35 and 40, respectively. RESULTS AND DISCUSSIONS In the case of the proband's father, the untreated polyps led to death after 12 years. The proband revealed a low number of polyps and an extra colon feature characteristic of AAPC, but the polyps onset and the death of CRC of two family members, who refused colectomy, was very early and characteristic for FAP. An atypical course of AAPC must be taken into consideration both in genetic counseling and in qualifying the patients with AAPC for the surgical treatment.

Abstract
Blastoderm cells from chicken embryos of a donor breed (Green-legged Partridgelike; GP) were transferred to embryos of a recipient breed (White Leghorn; WL) to form chimeric progeny that, after inter se mating, permitted successful reconstitution of the donor breed. Among 23 chimeric chicks hatched from WL embryos injected with GP cells, 20 (87%) were raised until maturity, and progeny were tested by mating with GP birds to determine the ability of blastodermal cells to form germline chimeras. Six of the tested birds (30%) produced recipient-derived and donor-derived offspring, indicating that they were germline chimeras. The mean percentages of donor-derived germ cells in these birds were 21.1 (17.6 to 50.0%) and 16.9 (5.3 to 23.1%) in males and females, respectively. Among 477 chicks, resulting from mating the germline chimeric male with four germline chimeric females, 10 chicks (2.1%) exhibited a GP phenotype, indicating that the original donor stock had been reconstituted. Only one germline chimeric hen produced GP offspring, but the expected and calculated percentages of GP offspring were similar (2.99 and 2.08, respectively). Two methods of DNA analyses (RFLP and PCR amplification of polymorphic microsatellite loci) of chimeras and their offspring indicated that through mating of a relatively small number of chimeras it is possible to reconstitute a highly diverse population.
