Core Tip
Core tip: Genetic predisposition might play important roles in the onset of osteonecrosis of the femoral head (ONFH) in systemic lupus erythematosus (SLE). Some gene loci such as complement C3d receptor 2 (CR2), nitric oxide synthase 3 (NOS3), collagen type II alpha 1 chain (COL2A1), protein tyrosine phosphatase non-receptor type 22 (PTPN22), and transient receptor potential cation channel subfamily V member 4 (TRPV4) were reported to be involved in this process. We investigated whether the risk of ONFH in SLE is associated with single nucleotide variations (SNVs) in these five genes by using FastTarget and Illumina Miseq sequencing technologies in 49 cases. Six patients were confirmed to have low frequency SNVs, including one in NOS3, four in COL2A1, and one in CR2. The onset of ONFH in SLE might be associated with the identified SNVs in NOS3, COL2A1, and CR2.
