Relation between anti- antibody titers and HLA-DRB1 neutral alleles in individuals with rheumatoid arthritis.

Objective: This study aimed to determine the relation between titres of anti- antibody and rheumatoid arthritis (RA) HLA-DRB1 susceptibility region associated with shared epitope (SE) using the Gregersen's and de Vries's classification methods.

Material And Methods: In this cross-sectional study, results of immunoglobulin G1 (IgG1) and immunoglobulin G2 (IgG2) anti-P. gingivalis antibodies, anti-citrullinated protein antibodies (ACPA), diagnosis for RA, and periodontal disease (PD), and a genetic study of the HLA DRB1 region were obtained from 50 patients with RA and 50 control individuals.

Hereditary leiomyomatosis and renal cell cancer syndrome: identification and clinical characterization of a novel mutation in the FH gene in a Colombian family.

Hereditary Leiomyomatosis and Renal Cell Cancer Syndrome (HLRCC) is a rare disease and since the first report, it has been found in just over 200 families approximately, around the world (Smit et al. in Clin Genet 79:49-59, 2009). Patients in Colombia or in Latin America have not been described, as far as we know.
