BACKGROUND Although G6PD deficiency is the most common genetically determined blood disorder among Iraqis, its molecular basis has only recently been studied among the Kurds in North Iraq, while studies focusing on Arabs in other parts of Iraq are still absent. METHODS A total of 1810 apparently healthy adult male blood donors were randomly recruited from the national blood transfusion center...
Rare individuals who lack all of the Rh blood group antigens are called Rhnull and may be classified as "regulator" or "amorph" types. The suppression of Rh antigen expression for regulator types may be attributed to mutations of the RH50 gene, which is independent of the RH locus. The RH50 gene encodes a glycoprotein that interacts with the Rh proteins to form a functional complex within the r...
OBJECTIVE Restriction analysis is a straightforward procedure for mutational analysis. It is commonly used for screening RET mutations. Incomplete digestion is a well-known cause of false results. Herein, we report another limitation of the method. DESIGN AND METHODS Screening for somatic mutations in RET exons 16, 13 and 15 was performed in a patient with a sporadic medullary thyroid carcino...
Human cancers carry hundreds of non-synonymous mutations, several dozens among which may lead to the generation of tumor-specific MHC Class I-restricted epitopes. Hence every patient's tumor harbors a highly specific mutational and antigenic signature and up to 95% of these mutations are unique. This "mutanome" can be identified by deep sequencing and can be subjected to systematic analyses of ...
Over the past decade, there has been both great interest and confusion about whether recent demographic events-notably the Out-of-Africa-bottleneck and recent population growth-have led to differences in mutation load among human populations. The confusion can be traced to the use of different summary statistics to measure load, which lead to apparently conflicting results. We argue, however, t...
Synonymous mutations, which do not alter the protein sequence, have been shown to affect protein function [Sauna ZE, Kimchi-Sarfaty C (2011) Nat Rev Genet 12(10):683-691]. However, synonymous mutations are rarely investigated in the cancer genomics field. We used whole-genome and -exome sequencing to identify somatic mutations in 29 melanoma samples. Validation of one synonymous somatic mutatio...
Many SNPs are predicted to encode deleterious amino acid variants. These slightly deleterious mutations can provide unique insights into population history, the dynamics of selection, and the genetic bases of phenotypes. This is especially true for domesticated species, where a history of bottlenecks and selection may affect the frequency of deleterious variants and signal a "cost of domesticat...
BACKGROUND Many facultative bacterial pathogens have undergone extensive gene decay processes, possibly due to lack of selection pressure during evolutionary conversion from free-living to intracellular lifestyle. Shigella, the causative agents of human shigellosis, have arisen from different E. coli-like ancestors independently by convergent paths. As these bacteria all have lost large numbers...
In previous studies 1-3 % of ALS patients have TARDBP mutations as the cause of the disease. TARDBP mutations have been reported in ALS patients in different populations but so far there are no studies on the frequency of TARDBP mutations in Finnish ALS patients. A cohort of 50 Finnish patients, 44 SALS and 6 FALS patients, were included in the study. Genomic DNA was extracted from venous blood...
Phosphorus (P) is one of the most vital elements for all living organisms which acts as aconstituent of essential biomolecules such as nucleic acids, phospholipids, and phosphosugars,and as a major contributor to almost all metabolic reactions including photosynthesis,respiration, and energy delivery. It is one of the most needed nutrients for plant growth anddevelopment. Despite high levels of...
