Study of the genetics of rheumatoid arthritis (RA) began about four decades ago with the discovery of HLA-DRB1 . Since the beginning of this century, a number of non-HLA risk loci have been identified through genome-wide association studies (GWAS). We now know that over 100 loci are associated with RA risk. Because genetic information implies a clear causal relationship to the disease, research into the pathogenesis of RA should be promoted. However, only 20% of GWAS loci contain coding variants, with the remaining variants occurring in non-coding regions, and therefore, the majority of causal genes and causal variants remain to be identified. The use of epigenetic studies, high-resolution mapping of open chromatin, chromosomal conformation technologies and other approaches could identify many of the missing links between genetic risk variants and causal genetic components, thus expanding our understanding of RA genetics.

13. Epidemiology and genetics of rheumatoid arthritis
May 9, 2002 · The main genetic risk factor of RA is the HLA DRB1 alleles, and this has consistently been shown in many populations throughout the world. The ...
The prevalence of rheumatoid arthritis (RA) is relatively constant in many populations, at 0.5–1.0%. However, a high prevalence of RA has been reported in the Pima Indians (5.3%) and in the Chippewa Indians (6.8%). In contrast, low occurrences have been reported in populations from China and Japan. These data support a genetic role in disease risk. Studies have so far shown that the familial recurrence risk in RA is small compared with other autoimmune diseases. The main genetic risk factor of RA is the HLA DRB1 alleles, and this has consistently been shown in many populations throughout the world. The strongest susceptibility factor so far has been the HLA DRB1*0404 allele. Tumour necrosis factor alleles have also been linked with RA. However, it is estimated that these genes can explain only 50% of the genetic effect. A number of other non-MHC genes have thus been investigated and linked with RA (e.g. corticotrophin releasing hormone, oestrogen synthase, IFN-γ and other cytokines). Environmental factors have also been studied in relation to RA. Female sex hormones may play a protective role in RA; for example, the use of the oral contraceptive pill and pregnancy are both associated with a decreased risk. However, the postpartum period has been highlighted as a risk period for the development of RA. Furthermore, breastfeeding after a first pregnancy poses the greatest risk. Exposure to infection may act as a trigger for RA, and a number of agents have been implicated (e.g. Epstein–Barr virus, parvovirus and some bacteria such as Proteus and Mycoplasma). However, the epidemiological data so far are inconclusive. There has recently been renewed interest in the link between cigarette smoking and RA, and the data presented so far are consistent with and suggestive of an increased risk.

If you have a close family member such as a sibling or parent with RA, you are three times more likely to develop RA than the general population.
FAQs
Is Rheumatoid Arthritis Genetic? ›
Evidence suggests that environmental factors may also play a role in RA as our genes and family history. In fact, the latest research shows that the risk of developing RA is linked to a combination of genetics, family history, and environmental triggers.
Is arthritis inherited from mother or father? ›If you have rheumatoid arthritis (RA) you may wonder if you inherited it from one of your parents or if you'll pass it along to your own children. Strictly speaking, neither scenario is the case: RA is not an inherited condition. However, a person's individual genetic make-up can increase the risk of developing RA.
Who is most likely to have rheumatoid arthritis? ›RA can begin at any age, but the likelihood increases with age. The onset of RA is highest among adults in their sixties. Sex. New cases of RA are typically two-to-three times higher in women than men.
Can you have rheumatoid arthritis if your rheumatoid factor is normal? ›Many people with rheumatoid arthritis have little or no rheumatoid factor. If you have symptoms of rheumatoid arthritis, but your RF test results are normal, your provider may order more tests to make a diagnosis. A positive (abnormal) result means that a higher level of rheumatoid factor was found in your blood.
What age does rheumatoid arthritis start? ›You can get rheumatoid arthritis (RA) at any age, but it's most likely to show up between ages 30 and 50. When it starts between ages 60 and 65, it's called elderly-onset RA or late-onset RA. Elderly-onset RA is different from RA that starts in earlier years. It also comes with a separate set of treatment challenges.
What is the genetic marker for rheumatoid arthritis? ›The most significant genetic risk factors for rheumatoid arthritis are variations in human leukocyte antigen (HLA) genes , especially the HLA-DRB1 gene. The proteins produced from HLA genes help the immune system distinguish the body's own proteins from proteins made by foreign invaders (such as viruses and bacteria).
What is the number one cause of rheumatoid arthritis? ›Researchers think it's caused by a combination of genetics, hormones and environmental factors. Normally, your immune system protects your body from disease. With rheumatoid arthritis, something triggers your immune system to attack your joints. An infection, smoking or physical or emotional stress may be triggering.
What are the triggers for rheumatoid arthritis? ›Rheumatoid Arthritis
This means flares can vary in intensity, duration and frequency, but they're usually reversible — if treated promptly. For most people, the flare risk increases when treatments are tapered or stopped. Other triggers include overexertion, stress, infection or poor sleep.
“A lot of us are starting to retire,” says Dr. Morris. “They're not keeping up with the number of rheumatologists retiring, which is a big problem.” The other aspect of this bottleneck is the lack of fellowship opportunities for those coming out of residency who want to specialize in rheumatology.
What diseases are misdiagnosed as rheumatoid arthritis? ›- Lyme Disease.
- Psoriatic Arthritis.
- Sjögren's Syndrome.
- Gout.
- Fibromyalgia.
- Lupus.
Is lupus or RA worse? ›
Lupus is more likely to affect your internal organs and skin than RA. Lupus can also cause life threatening complications, which may include: kidney failure. blood clotting problems.
Who is most likely to inherit arthritis? ›There is an inherited component to RA. Research shows that the disease rate is 0.5% in the general population and 0.8% among those with a family history of RA; genetically European people with RA are at least twice as likely as unaffected people to carry the HLA-DR4 gene.
What age does genetic arthritis start? ›What Causes Systemic Juvenile Idiopathic Arthritis? All types of JIA happen when the immune system, which normally attacks germs, mistakenly attacks the joints. This causes inflammation (swelling and irritation) in the joints and other problems. Systemic JIA can start anytime in kids 1 to 16 years old.
Is arthritis more common in males or females? ›Not only do women get more arthritis than men (one in four compared to one in five), but women also often experience worse pain –ache in different joints – and are far more vulnerable to rheumatoid arthritis, one of the most debilitating forms of the condition.
How can inherited arthritis be prevented? ›- Maintain a Healthy Weight. ...
