Mutations of the transmembrane channel-like gene 1 (TMC1) have been shown to cause autosomal dominant and recessive forms of congenital nonsyndromic deafness linked to the loci DFNA36 and DFNB7/B11, respectively. In a Sudanese pedigree affected by an apparently recessive form of nonsyndromic deafness, we performed a linkage analysis using markers covering(More)
SETTING Host genetic risk factors influence susceptibility to tuberculosis (TB). There is ample evidence supporting the involvement of toll-like receptor 4 (TLR4) in mycobacterial infection. OBJECTIVE To study the relationship between the TLR4 gene and TB susceptibility in the Sudanese population. DESIGN A case-control study was conducted among 207(More)
A large proportion of non-syndromic autosomal recessive deafness (NSARD) in many populations is caused by variants of the GJB2 gene. Here, the frequency of GJB2 variants was studied in 406 and 183 apparently unrelated children from Kenya and Sudan, respectively, with mostly severe to profound non-syndromic deafness. Nine (2.2 %) Kenyan and 12 (6.6 %) of the(More)
Abnormal fibrosis occurs during chronic hepatic inflammations and is the principal cause of death in hepatitis C virus and schistosome infections. Hepatic fibrosis (HF) may develop either slowly or rapidly in schistosome-infected subjects. This depends, in part, on a major genetic control exerted by genes of chromosome 6q23. A gene (connective tissue growth(More)
Quality-assessed biomedical samples are essential for academia- and industry driven research on human diseases. The etiologies and the molecular genetic factors relevant in African diseases, including both infections and complex degenerative diseases as well as cancer, need to be studied using well annotated and well-preserved biosamples acquired from(More)
The main objective of this study is to provide a database for renal transplantation in Sudan and to determine the HLA antigens and haplotype frequencies (HFs) in the study subjects. HLA typing was performed using the complement-dependant lymphocytotoxicity test in 250 unrelated healthy individuals selected as donors in the Sudanese Renal Transplantation(More)
SETTING: Host genetic risk factors influence the susceptibility to tuberculosis (TB). There is ample evidence supporting the involvement of toll-like receptor 4 (TLR4) in mycobacterial infection. OBJECTIVE: To study the relationship between the TLR4 gene and TB susceptibility in Sudanese. DESIGN: A case-control study was conducted by recruiting 207 patients(More)
BACKGROUND New immunization programs are dependent on data from surveillance networks and disease burden estimates to prioritize target areas and risk groups. Data regarding invasive Salmonella disease in sub-Saharan Africa are currently limited, thus hindering the implementation of preventive measures. The Typhoid Fever Surveillance in Africa Program(More)
BACKGROUND Esophageal cancer (EC) is among the most common malignancies in Eastern Africa, but the occurrence of EC in Sudan has rarely been described in the scientific literature. This paper reports the results of a consecutive case series of all EC patients who visited one of the two public cancer treatment centers in the country in 1999-2012, providing a(More)
BACKGROUND Country-specific studies in Africa have indicated that Plasmodium falciparum is associated with invasive nontyphoidal Salmonella (iNTS) disease. We conducted a multicenter study in 13 sites in Burkina Faso, Ethiopia, Ghana, Guinea-Bissau, Kenya, Madagascar, Senegal, South Africa, Sudan, and Tanzania to investigate the relationship between the(More)
