Clinical characteristics of a KIF21A mutation in a Chinese family with congenital fibrosis of the extraocular muscles type 1.

The aim of the study is to characterize the clinical ocular phenotype with congenital fibrosis of the extraocular muscles type 1 (CFEOM1) and to confirm whether the kinesin family member 21A (KIF21A) mutation was the pathogenic gene in this Chinese family.Three affected individuals and 2 asymptomatic kinsfolk from a Chinese family underwent comprehensive ophthalmic examinations, orbital computerized tomography (CT), and postoperative histological examinations were performed in the proband. All the recruited members were screened for 3 exons (8, 20, and 21) of KIF21A mutations using the polymerase chain reaction (PCR) amplification and direct sequencing of corresponding PCR products.

rs3806268 of NLRP3 gene polymorphism is associated with the development of primary gout.

The aim of the present study was to investigate the association between seven functional SNPs in NALP3 gene and the susceptibility to primary gout. A total of 247 patients with primary gout and 247 controls were selected in this study. Genotyping of NALP3 rs4612666, rs3806268, rs12239046, rs10754558, rs7512998, rs12137901 and rs12565738 was performed using the Sequenom MassARRAY platform.
