TNFAIP3 represents a possible inflammatory candidate gene that could influence fertility, as TNFAIP3 regulates inflammation through control of NF-κB which in turn influences many aspects of fertility, and GWAS data link TNFAIP3 SNPs with autoimmune diseases with female bias and associated infertility (i.e. with SLE, RA and MS). The gene discussed is NFKB1; the disease is rheumatoid arthritis.
