CR1 allelic distribution in healthy italians and SLE patients

2010

Complement receptor type 1 (CR1; CD35), the receptor for C3b/C4b, has a molecular weight polymorphism involving four co-dominantly expressed alleles CR1*1, CR1*2, CR1*3 and CR1*4. The most common allotype in the Caucasian population is CR1*1. Previous studies on the frequency of the CR1 allele in Systemic Lupus Erythematosus (SLE) patients reported conflicting results. Recently an increased frequency of the CR1*2 allele was reported in Caucasian SLE patients. The aim of our study is to assess the frequency of CR1 structural alleles in a sample of the Italian population and in a cohort of Italian SLE patients equally distributed nationwide. We found that the most common phenotype was CR1*1.1…
