👉 Telangiosis is a genetic disorder that affects the growth of the fingers, feet, and hands. It can be caused by mutations in the telangiectin gene, which is involved in regulating blood flow to the skin and nails. The condition results from an abnormal buildup of telangiectin in these areas, leading to uneven or abnormal growth. Treatment options for telangiosis include surgery to correct the abnormal growth, as well as medications to manage symptoms such as pain and inflammation.
