The Effect of Oral Contraceptive Pills on The Gene Mutation of Factor V Leiden among Sudanese Women

Oral contraceptive pills are problems for women, often have many effects, and may cause several diseases. The purpose of this research was to determine the impact of oral contraceptive pills on factor V sufferers. This case-control study conducted in Khartoum Sudan during the period from April to November 2018. The study included 50 women who used oral contraceptive as a case and 50 women who did not use oral contraceptive pills as a control, all of whom were verbally informed of the study and approved for participation. The PCR do for each sample. The results obtained from cases show that the mean age is 30±5.5 and divided into three groups less than 20 with a lower frequency of 4 % (2/50), (20-35) with a higher incidence of 80 % (40/50) and a higher rate of 16 % (8/50) for more than 35 years. Most cases use the oral contraceptive pill for more than one year at a frequency of 60% (30/50) with a mean of 2±0.8. The most frequent oral contraceptive pill use was levonorgestrel 88% (44/50), followed by desogestrel 12% (6/50). The study concludes that there is no significant difference in gene mutation between case and control. There was also an insignificant association between the mutation and demographic data

Genetic variation and population structure of Sudanese populations as indicated by 15 Identifiler sequence-tagged repeat (STR) loci

<p>Abstract</p> <p>Background</p> <p>There is substantial ethnic, cultural and linguistic diversity among the people living in east Africa, Sudan and the Nile Valley. The region around the Nile Valley has a long history of succession of different groups, coupled with demographic and migration events, potentially leading to genetic structure among humans in the region.</p> <p>Result</p> <p>We report the genotypes of the 15 Identifiler microsatellite markers for 498 individuals from 18 Sudanese populations representing different ethnic and linguistic groups. The combined power of exclusion (PE) was 0.9999981, and the combined match probability was 1 in 7.4 × 10¹⁷. The genotype data from the Sudanese populations was combined with previously published genotype data from Egypt, Somalia and the Karamoja population from Uganda. The Somali population was found to be genetically distinct from the other northeast African populations. Individuals from northern Sudan clustered together with those from Egypt, and individuals from southern Sudan clustered with those from the Karamoja population. The similarity of the Nubian and Egyptian populations suggest that migration, potentially bidirectional, occurred along the Nile river Valley, which is consistent with the historical evidence for long-term interactions between Egypt and Nubia.</p> <p>Conclusion</p> <p>We show that despite the levels of population structure in Sudan, standard forensic summary statistics are robust tools for personal identification and parentage analysis in Sudan. Although some patterns of population structure can be revealed with 15 microsatellites, a much larger set of genetic markers is needed to detect fine-scale population structure in east Africa and the Nile Valley.</p

First steps towards the detection of contact layers in Bangime: A multi-disciplinary, computer-assisted approach

We present a computer-assisted, multidisciplinary, first approach to addressing this problem of detecting the layers of contact in Bangime. First, we assemble lexical evidence of contact between Bangime speakers with their neighboring languages, using a computer-assisted technique, followed by an evaluation of the materials by contrasting them with genetic findings. Specifically, we propose trajectories for Bangande settlement patterns. With this study, we lay the foundation of future collaborative work that will improve, correct, and enhance the results of this study. The original data used for the study are made available so that additional researchers may follow up on and test our hypotheses concerning contact layers in Bangime

Genomic resources for wild populations of the house mouse, Mus musculus and its close relative Mus spretus

WOS: 000390231600001PubMed ID: 27622383Wild populations of the house mouse (Mus musculus) represent the raw genetic material for the classical inbred strains in biomedical research and are a major model system for evolutionary biology. We provide whole genome sequencing data of individuals representing natural populations of M. m. domesticus (24 individuals from 3 populations), M. m. helgolandicus (3 individuals), M. m. musculus (22 individuals from 3 populations) and M. spretus (8 individuals from one population). We use a single pipeline to map and call variants for these individuals and also include 10 additional individuals of M. m. castaneus for which genomic data are publically available. In addition, RNAseq data were obtained from 10 tissues of up to eight adult individuals from each of the three M. m. domesticus populations for which genomic data were collected. Data and analyses are presented via tracks viewable in the UCSC or IGV genome browsers. We also provide information on available outbred stocks and instructions on how to keep them in the laboratory.Max-Planck Society; DFG [HA 3139/4-1]; ERC [322564]; contract-research-project for the Bundeswehr Medical Service [M/SABX/005]This work was mostly financed by institutional resources of the Max-Planck Society, a DFG grant to B.H. and M.T.

The Genetic Variation of Lactase Persistence Alleles in Sudan and South Sudan

Lactase persistence (LP) is a well-studied example of a Mendelian trait under selection in some human groups due to gene-culture coevolution. We investigated the frequencies of genetic variants linked to LP in Sudanese and South Sudanese populations. These populations have diverse subsistence patterns, and some are dependent on milk to various extents, not only from cows but also from other livestock such as camels and goats. We sequenced a 316-bp region involved in regulating the expression of the LCT gene on chromosome 2, which encompasses five polymorphisms that have been associated with LP. Pastoralist populations showed a higher frequency of LP-associated alleles compared with nonpastoralist groups, hinting at positive selection also among northeast African pastoralists. Among the LP variants, the -14009:G variant occurs at the highest frequency among the investigated populations, followed by the -13915:G variant, which is likely of Middle Eastern origin, consistent with Middle Eastern gene flow to the Sudanese populations. There was no incidence of the “East African” LP allele (-14010:C) in the Sudanese and South Sudanese groups, and only one heterozygous individual for the “European” LP allele (-13910:T), suggesting limited recent admixture from these geographic regions. The Beja population of the Beni Amer show three different LP variants at substantial and similar levels, resulting in one of the greatest aggregation of LP variants among all populations across the world.Title in thesis list of papers: The genetic variation of lactase persistence alleles in northeast Africa</p

Northeast African genomic variation shaped by the continuity of indigenous groups and Eurasian migrations

Northeast Africa has a long history of human habitation, with fossil-finds from the earliest anatomically modern humans, and housing ancient civilizations. The region is also the gateway out of Africa, as well as a portal for migration into Africa from Eurasia via the Middle East and the Arabian Peninsula. We investigate the population history of northeast Africa by genotyping similar to 3.9 million SNPs in 221 individuals from 18 populations sampled in Sudan and South Sudan and combine this data with published genome-wide data from surrounding areas. We find a strong genetic divide between the populations from the northeastern parts of the region (Nubians, central Arab populations, and the Beja) and populations towards the west and south (Nilotes, Darfur and Kordofan populations). This differentiation is mainly caused by a large Eurasian ancestry component of the northeast populations likely driven by migration of Middle Eastern groups followed by admixture that affected the local populations in a north-to-south succession of events. Genetic evidence points to an early admixture event in the Nubians, concurrent with historical contact between North Sudanese and Arab groups. We estimate the admixture in current-day Sudanese Arab populations to about 700 years ago, coinciding with the fall of Dongola in 1315/1316 AD, a wave of admixture that reached the Darfurian/Kordofanian populations some 400-200 years ago. In contrast to the northeastern populations, the current-day Nilotic populations from the south of the region display little or no admixture from Eurasian groups indicating long-term isolation and population continuity in these areas of northeast Africa

Data from: Northeast African genomic variation shaped by the continuity of indigenous groups and Eurasian migrations

Northeast Africa has a long history of human habitation, with fossil-finds from the earliest anatomically modern humans, and housing ancient civilizations. The region is also the gate-way out of Africa, as well as a portal for migration into Africa from Eurasia via the Middle East and the Arabian Peninsula. We investigate the population history of northeast Africa by genotyping ~3.9 million SNPs in 221 individuals from 18 populations sampled in Sudan and South Sudan and combine this data with published genome-wide data from surrounding areas. We find a strong genetic divide between the populations from the northeastern parts of the region (Nubians, central Arab populations, and the Beja) and populations towards the west and south (Nilotes, Darfur and Kordofan populations).
