Systemic lupus erythematosus (SLE) is an autoimmune disorder characterized by production of autoantibodies against intracellular antigens including DNA, ribosomal P, Ro (SS-A), La (SS-B), and the spliceosome. Etiology is suspected to involve genetic and environmental factors. Evidence of genetic involvement includes: associations with HLA-DR3, HLA-DR2, Fcγ receptors (FcγR) IIA and IIIA, and hereditary complement component deficiencies, as well as familial aggregation, monozygotic twin concordance >20%, λs > 10, purported linkage at 1q41–42, and inbred mouse strains that consistently develop lupus. We have completed a genome scan in 94 extended multiplex pedigrees by using model-based linkage analysis. Potential [log10 of the odds for linkage (lod) > 2.0] SLE loci have been identified at chromosomes 1q41, 1q23, and 11q14–23 in African-Americans; 14q11, 4p15, 11q25, 2q32, 19q13, 6q26–27, and 12p12–11 in European-Americans; and 1q23, 13q32, 20q13, and 1q31 in all pedigrees combined. An effect for the FcγRIIA candidate polymorphism) at 1q23 (lod = 3.37 in African-Americans) is syntenic with linkage in a murine model of lupus. Sib-pair and multipoint nonparametric analyses also support linkage (P < 0.05) at nine loci detected by using two-point lod score analysis (lod > 2.0). Our results are consistent with the presumed complexity of genetic susceptibility to SLE and illustrate racial origin is likely to influence the specific nature of these genetic effects.

This dissertation examines African-American Islamic culture from 1920 through 1959, a period I label the "African-American Islamic Renaissance" (AAIR). The AAIR is characterized by a significant increase in interest in Islam, extreme diversity in views about Islam, and the absence of a single organization dominating African-American Islamic culture for a significant amount of time. Previous works dealing with African-American Islam in this period have failed to fully recognize these features, particularly the last of these. As a result, explanations for the rise of the Nation of Islam (NOI) have not satisfactorily explained why it was only the NOI--and not other Islamic groups that were more popular than the NOI up until the mid-1950s--that became a "mass movement," gaining the allegiance of tens of thousands of African Americans. There has been some tendency, for instance, to assume that the NOI was the most popular African-American Islamic group by the early 1950s, a notion that is probably an inference drawn from two other popular but inaccurate assumptions: that the NOI's rise was due primarily to its radical racialized doctrines and its charismatic leaders, particularly Malcolm X, who became a popular minister for the group in the early 1950s. I argue, however, that the NOI was in fact not the most popular African-American Islamic group until at least 1955, and even as late as 1959 its official membership numbers were not particularly large by AAIR standards. Also, its doctrines were not especially unique in the AAIR, nor was its having extremely charismatic leaders. I contend that the success of the NOI in the mid-to-late 1950s was the result of three levels of changes at the time: internal, external in the AAIR community, and external in the broader U.S, culture.
