Scientists Spot Genes Linked to Raynaud's Phenomenon
Raynaud's Phenomenon is where blood flow decreases to the fingertips and other body parts. It can occur independently or alongside other diseases such as lupus, scleroderma, and Buerger disease. The exact cause of this phenomenon is unknown but in recent findings, scientists have discovered two genes that may trigger it. They have identified the two specific genes that trigger specific mechanisms. The article states “About half the people who have primary Raynaud’s phenomenon have another first-degree relative who also has Raynaud’s,” The scientists found that one gene variant affects how the blood vessels narrow. The people with the variant had a higher number of specific receptors for the hormones that are released under stress or the cold. The second gene affects how the blood vessels react. This is the first study to identify compelling information on Raynaud's phenomenon.
