Evaluation of NLRP1 gene polymorphisms in Vogt-Koyanagi-Harada disease.
Summary of "Evaluation of NLRP1 gene polymorphisms in Vogt-Koyanagi-Harada disease."
PURPOSE:
Polymorphisms of the NACHT [neuronal apoptosis inhibitory protein (NAIP), CIITA, HET-E, TP1] and leucine-rich repeat protein 1 (NLRP1) gene are reported to be associated with susceptibility to vitiligo and several autoimmune diseases. Vogt-Koyanagi-Harada (VKH) disease is an autoimmune disorder affecting melanocytes in the skin, eyes, inner ear, and meninges. In this study, genetic associations between VKH disease and single-nucleotide polymorphisms (SNPs) surrounding the NLRP1 gene were investigated.
METHODS:
Six SNPs (rs6502867, rs925597, rs3926687, rs2733359, rs878329, and rs4790796) near the NLRP1 gene, including noncoding regions, were sequenced by a direct method to genotype 167 Japanese patients with VKH disease and 187 healthy Japanese volunteers.
RESULTS:
None of the six SNPs in the NLRP1 region were significantly associated with disease susceptibility or the ocular, neurological, and dermatological manifestations of VKH.
CONCLUSIONS:
Although skin manifestations are clinically similar between vitiligo and VKH disease, the genetic and immunological mechanisms of these two diseases may be different.

Medical and Biotech [MESH] Definitions
Evaluation Studies As Topic
Studies determining the effectiveness or value of processes, personnel, and equipment, or the material on conducting such studies. For drugs and devices, CLINICAL TRIALS AS TOPIC; DRUG EVALUATION; and DRUG EVALUATION, PRECLINICAL are available.
Peptide Mapping
Analysis of PEPTIDES that are generated from the digestion or fragmentation of a protein or mixture of PROTEINS, by ELECTROPHORESIS; CHROMATOGRAPHY; or MASS SPECTROMETRY. The resulting peptide fingerprints are analyzed for a variety of purposes including the identification of the proteins in a sample, GENETIC POLYMORPHISMS, patterns of gene expression, and patterns diagnostic for diseases.
Program Evaluation
Studies designed to assess the efficacy of programs. They may include the evaluation of cost-effectiveness, the extent to which objectives are met, or impact.
Ventricular Function, Left
The hemodynamic and electrophysiological action of the left HEART VENTRICLE. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance.
Gene Dosage
The number of copies of a given gene present in the cell of an organism. An increase in gene dosage (by GENE DUPLICATION for example) can result in higher levels of gene product formation. GENE DOSAGE COMPENSATION mechanisms result in adjustments to the level GENE EXPRESSION when there are changes or differences in gene dosage.
