Is there a link between HepC from blood transfusion with infected blood and RA?

Hi there pxa1eb, Thanks for reaching out. Although the cause of RA is unknown, a leading explanation for why RA and other autoimmune disorders develop is that some environmental exposure or other non-genetic factor triggers the disease in individuals who are already genetically susceptible.

Hi pxa1eb. Just wanted to follow-up on the excellent information provided by Kelly. She mentioned that RA often develops due to a trigger in those already genetically susceptible. The genetic component is not completely understood, but more is being learned all the time. This article from our editorial team looks at genetic factors, including how the genetic risk for RA is determined: https://rheumatoidarthritis.net/causes/genetic-factors-and-family-history/.
