Heritability Of Autoantibody Levels In A Twin Population, Amal Rastogi
Heritability Of Autoantibody Levels In A Twin Population, Amal Rastogi
Theses and Dissertations
AIM: This study aims to determine what portion of specific autoantibody phenotypes are genetically determined by using a twin model. METHODS: This study specifically examines Anti-Ro(SSA), Anti-La (SSB), Anti-Sn/RNP, Anti-Sm, Anti-Jo-1, Anti-Scl-70, Anti-Tg & Anti-TPO, Anti-dsDNA, Anti-PS, and Anti-cardiolipin antibodies for their heritability. This study examined 104 same-sex adult twins (66 monozygous, 38 dizygous) for the above mentioned autoantibody values. The serum autoantibody values in each subject were quantified using automated ELISA. Descriptive statistics including, distributions, quantiles, and moments were calculated by zygosity for continuous antibody values, subject ages, gender, race and smoking status. Categorical antibody levels were used to …
The Effect Of Single Nucleotide Polymorphisms (Snps) In Toll-Like Receptors -2, -4, -9, And Cd14 Genes In An African-American Population With Chronic Periodontitis, Willard Maughan
Theses and Dissertations
AIM: to determine if a relationship exists between TLR-2, TLR-4, TLR-9, or CD14 polymorphisms and risk for developing chronic periodontal disease in an African-American population. This is the first study conducted to determine role of SNPs in TLR genes and CD14 gene in a periodontally-diseased African-American population. Additionally, this is the first study to assess the role of TLR-9 polymorphism in periodontitis patients. METHODS: A total of 130 subjects were involved in the study. The chronic periodontitis (CP) group contained 73 subjects, and the healthy control (NP) group 57subjects. Genotyping was performed in TLR2 (G2408A), TLR4 (A896G),TLR9 (T1486C) and CD14 …
Frequency Of Tlr-2, 4, 9 And Cd14 Polymorphisms In Aggressive Periodontitis Population In African-Americans, Melanie Chou
Frequency Of Tlr-2, 4, 9 And Cd14 Polymorphisms In Aggressive Periodontitis Population In African-Americans, Melanie Chou
Theses and Dissertations
Aim: The aim of this study is to determine the frequency of single nucleotide polymorphisms (SNPs) in various pattern recognition receptor (PRR) genes, including Toll like receptors (TLR) -2, -4, -9, and CD14 in chronic (CP), localized (LAP) and generalized aggressive (GAP) periodontitis and periodontally healthy (NP) patients in an African American population. Methods: A total of 205 subjects were involved in the study. The LAP group consists of 25 subjects, the GAP group 50 subjects, the CP group 73 subjects and the NP group 57subjects. Genotyping was performed in TLR2 (G2408A), TLR4 (A896G),TLR9 (T1486C) and CD14 (C260T) genes by …
