Zusammenfassung: | Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease characterized by the production of a wide range of autoantibodies, resulting in tissue damage. Although the susceptibility to SLE has been attributed to complex interactions between genetic and environmental factors, the influence of a genetic predisposition to SLE is supported by observations of familial aggregations. Family studies have found that siblings with an SLE-affected relative have a 20-fold higher risk of developing SLE compared with the general population. Here, we present a rare case of two male siblings with SLE. The clinical, laboratory, and histopathological findings of these individuals showed the characteristic features of SLE. Human leukocyte antigen (HLA) typing revealed that the brothers and their mother shared the common HLA haplotype of DRB1*1501 and DQB1*0602, which is significantly associated with disease susceptibility in both family-based and casecontrol studies. This report provides an opportunity to reveal the role of genetic factors in the development of SLE. 전신 홍반 루푸스는 자가 항원에 대한 자가 항체를 생성하여 염증을 일으켜 다양한 기관에 손상을 주는 자가 면역 질환이다. 발병 원인은 잘 알려져 있지 않으나, 전신 홍반 루푸스 환자의 가족 중에 전신 홍반 루푸스가 일반인보다 20배 이상 발병 위험이 높아 유전적인 요인이 관련되어 있을 것으로 생각된다. 저자들은 형제에서 발병한 가족성 전신 홍반 루푸스 증례를 경험하였고, 전신 홍반 루푸스와 연관된 조직적합 유전자인 HLA DRB1*1501과 DQB1*0602 유전자를 환아모와 형제들이 공유한 것을 발견하였기에 문헌 고찰과 함께 보고하는 바이다. |
