Abstract
Objectives: The aim of the present study was to evaluate the clinical relevance of mutations in
tumor suppressor genes using whole-exome sequencing data from centenarians and young
healthy individuals. Methods: Two pools, one of centenarians and one of young individuals, were constructed and
whole-exome sequencing was performed. We examined the whole-exome sequencing data of
Bulgarian individuals for carriership of tumor suppressor gene variants. Results: Of all variants annotated in both pools, 5080 (0.06%) are variants in tumor suppressor
genes but only 46 show significant difference in allele frequencies between the two
studied groups. Four variants (0.004%) are pathogenic/risk factors according to single
nucleotide polymorphism database: rs1566734 in PTPRJ, rs861539 in
XRCC3, rs203462 in AKAP10, and rs486907 in
RNASEL. Discussion: Based on their high minor allele frequencies and presence in the centenarian group, we
could reclassify them from pathogenic/risk factors to benign. Our study shows that
centenarian exomes can be used for re-evaluating the clinically uncertain variants.

Abstract
Chronic myeloid leukemia (CML) is one of the most common hematological malignancies and accounts for 15-20% of all leukemia cases. The cytogenetic marker of CML is the presence of Philadelphia chromosome (Ph) in >95% of patients. The current case reports a 83-year old woman who was directed to the genetic laboratory for a cytogenetic and molecular-genetic analysis suspected to be Ph positive [(+)]. Karyotype analysis of a bone marrow sample revealed a hyperdiploid karyotype in a part of Ph (+) cells with additional chromosomes 8, 10 and 12. Restriction analysis for V617F JAK2 mutation was negative, while the quantitative RT-qPCR assay indicated BCR-ABL/ABL transcript at the level of 120% International Scale (IS). Generally cytogenetic complexities are important in the prognostic evaluation of CML. Besides the Ph chromosome, a variet of chromosomal aberrations may be associated with CML. A total of 5-10% of these cases show complex translocations involving another chromosome. The current case is Ph(+) demonstrating an additional hyperdiploid karyotype clone with three additional autosomes (8, 10 and 12). This case highlights the significance of cytogenetic abnormalities on the prognosis of CML.

Abstract
Genome disbalances are related to the different types of infertility and they play a role in the treatment of human infertility. Comparative genome hybridization (CGH) combined with microchips is a modern high resolution technique for all human chromosomes investigations. We analysed the genome disbalances in 16 blood samples of men with an idiopathic oligoastenozoospermia or azoospermia using CGH and microchips for the whole human genome. Our data showed a few affected loci, including: 3q26.32 deletion accompanied by 14q11.1 deletion, 9q12 deletion, 5q35.1 amplification, 7p22.3 amplification and 17q12-17q21.2 amplification. In this study we have match the deletions: in two patients in the same area in the 8 chromosome, as well as in 5 patients in 14 chromosome. The deleted region contains 25 genes. Two of them (SPAG11B and SPAG11A) are associated with stages of spermatogenesis and in particular formation and maturation of the spermatozoa. These genes play a role during spermatogenesis and fertilization. Loss. chr.14q11.2 (EDDM3A and EDDM3B) affected the proteins that are synthesized and secreted by epididymal epithelial cells that has been found up-regulated in epididimis of nonobstructive azoospermic men. Our results displayed the significance of CGH and microchip analysis as a promising area of research with serious clinical application for resolving the problems of the male infertility and still have an important annex for selecting the most appropriate methods for the treatment in these patients as a perspective scientific field of investigations with a clinical appliance.
