Genetic factors predisposing individuals to Behet’s disease(BD) are considered to play important roles in the developmentof the disease. Patients with BD exhibit elevated levels of proinflammatory cytokines, and affected organs show a significant neutrophil and lymphocyte infiltration. Current evidence suggests that the activated lymphocytes contribute to neutrophil and endothelial cell activation in these patients. The cytotoxic T lymphocyte-associated antigen (CTLA)-4 molecule plays an important role in immune regulation by downregulating T-cell activation, and the CTLA-4 49A/G polymorphism in the exon 1 has been shown to be associated with a number of autoimmune diseases. In an attempt to demonstrate whether there is an association of the CTLA-4 49A/G polymorphism with BD in the Turkish population, we genotyped 59 Turkish patients and 99 healthy individuals for single-nucleotide polymorphisms. For this purpose, genomic DNA was obtained from the peripheral blood of individuals and the region of interest was amplified using PCR. Genotyping was performed using the BbvI restriction endonuclease. It was shown that the distribution of the CTLA-4 exon 1 49A/G allele and genotype frequencies did not differ between patientswith BD and healthy ***, allele and genotype frequencies of CTLA-4 49 A and A/A were significantly higher in patients with ocular involvement compared with patients without these symptoms (90.6%vs. 65.1%, odds ratio (OR) = 9.67, P = 0.011; and 81.25%vs. 39.5%,OR = 9.56, P = 0.015, respectively). A statistically significant difference in the A allele frequency was observed in patients with erythema nodosum-like lesions (86.1%vs. 65.8%, OR =6.24, P = 0.04). There was also an increase in A/A genotype frequency, but the difference was not statistically significant (72.2%vs. 41.5%, OR = 6.5, P = 0.068). Our data suggest that BD patients with ocular involvement and erythema nodosumlike lesions have a higher frequency of both the A allele and the

羊膜带综合征(amniotic band syndrome sequence,ABS)是一种罕见的可引起胚胎或胎儿受累器官或肢体出现分裂、截断或发育异常的复合畸形[1],因其破坏程度不同,临床表现程度亦不一[2],国内产前超声报道少见。目前由于部分超声医师对于此类畸形认识不足,故孕早期产前诊断率较低。现将本院发现的1例早孕期羊膜带综合征胎儿报告如下。
