caption_attribution_description: English: The earlobe crease of the Japanese angina patient
context_page_description: Frank's sign is a diagonal crease in the ear lobe extending from the tragus across the lobule to the rear edge of the auricle. The sign is named after Sanders T. Frank.
  It has been hypothesised that Frank's sign is indicative of cardiovascular disease and/or diabetes. Some studies have described Frank's sign as a marker of cardiovascular disease but not linked to the severity of the condition. In contrast, other studies have rebutted any association between Frank's sign and coronary artery disease in diabetics. There have also been reported cases of Frank's sign assisting in the diagnosis of cerebral infarctions. A link between Frank's sign and premature aging and the loss of dermal and vascular fibers has also been hypothesized. Some studies have focused upon bilateral ELC.
