Breakthrough Tool Decodes Lupus Genes, Paving the Way for Personalized Treatments

This discovery not only deepens our understanding of lupus onset but could also lead to tailored treatments based on individual genetic profiles.{vi2}

\”We’ve made two significant breakthroughs,\” said Professor Bae Sang-cheol of Hanyang University Hospital for Rheumatic Diseases, who led the study, in an exclusive interview with our correspondent.{vi4}
\”First, we’ve cracked the code on analyzing the notoriously complex immune-related genes in the MHC region of chromosome 6. Our new tool makes this analysis both accurate and accessible. This breakthrough lays the groundwork for uncovering genetic causes not just for lupus, but potentially for other autoimmune diseases like rheumatoid arthritis and inflammatory bowel disease as well.\”{vi6}
The study, a collaborative effort involving Professor Kim Kwangwoo at Kyung Hee University and the National Institute of Health’s genome research department, focused on the Major Histocompatibility Complex (MHC) region of our DNA.{vi8}
This crucial section of our genetic code is a key player in immune system regulation. It houses important genes like HLA and C4, both long suspected to have ties to autoimmune diseases, according to Bae.{vi10}

Lupus, or systemic lupus erythematosus, is an autoimmune condition where the body’s defense system turns against its own healthy cells and organs.{vi13} Bae Sang-cheol of Hanyang University Hospital for Rheumatic Diseases]Its impact can be widespread, affecting the skin, joints, kidneys, brain, and other organs. While scientists have long suspected a genetic component to lupus susceptibility, pinpointing the exact genes involved has been a Herculean task. Until now, researchers had identified up to 200 genes that could potentially play a role.{vi15}

The newly developed MHC imputation reference panel will enable more detailed analysis of this complex genomic region, marking a significant step toward understanding lupus at the genetic level. This advancement promises to shed light on why some individuals develop lupus and how their immune systems malfunction.{vi17}
The second major advancement, Bae explained, lies in the realm of precision medicine.{vi19}
\”Lupus isn’t like other genetic disorders caused by one or two mutations,\” he said. \”It’s a perfect storm of multiple genetic factors combined with environmental triggers, which has made identifying its cause extremely challenging.\”{vi21}
\”But now, by unraveling these complex combinations, we’re moving towards truly personalized treatment. For instance, if we identify that a patient’s lupus is linked to the C4 gene – one of the strongest known genetic risk factors – we can select a drug that specifically targets that mechanism. This opens up possibilities not just for more effective therapies, but for developing entirely new drugs.\”{vi23}
What sets this tool apart is not just its precision, but its cultural relevance.{vi25}
\”Most existing panels were built using data from U.S. populations,\” Bae explained. \”They often missed East Asian-specific genetic variations, reducing their accuracy for Koreans and other Asian populations. Our tool dramatically improves precision for these groups. It’s a significant milestone to see Korea and other East Asian countries leading the charge in this field.\”{vi27}
The new panel will be made publicly available through Korea’s national CODA system, allowing researchers worldwide to access it for studies on lupus, other autoimmune disorders, infectious diseases, and chronic inflammatory illnesses.{vi29}
\”This is just the tip of the iceberg,\” Bae concluded. \”Autoimmune diseases are even more complex than cancer due to the vast variability in genetic combinations from person to person. But if we can categorize individuals by their genetic profiles and match them with the right drugs, it could usher in an era of precision treatment for everyone.\”{vi31}
The groundbreaking study was published in Annals of the Rheumatic Diseases, one of the most prestigious international journals in the field.{vi33}
