Tóm tắt

Gen gây ra tình trạng hemochromatosis di truyền đã được chứng minh là liên kết chặt chẽ với các vị trí HLA-A và D6S105 trên cánh ngắn của nhiễm sắc thể 6. Tuy nhiên, các nỗ lực xác định bản đồ gen gây bệnh đã bị cản trở bởi sự thiếu hụt các recombinants có thông tin trong khu vực này. Chúng tôi đã xác định được hai cá thể recombinant trong một gia đình bị ảnh hưởng và đã xác nhận sự tái tổ hợp (recombination) thông qua phân tích 16 dấu hiệu di truyền đa hình nằm gần HLA-A và D6S105. Một trong các recombinants cung cấp bằng chứng về vị trí của gen hemochromatosis nằm ở vùng telomeric của HLA-F.
