Human folded ears are a genetic defect caused by congenital underdevelopment. Currently, there is no way to prevent it. The only way to prevent it is through later plastic surgery. However, people rarely have folded ears.

The so-called gene defect refers to the loss, inversion, or overlap of DNA segments or base pairs that control certain regulatory mechanisms of the human body, causing certain diseases, such as nucleotide deletions or mutations.

Scientists have identified six common genetic defects that are significantly related to the risk of heart disease. This discovery could save tens of thousands of lives by allowing doctors to more accurately assess risks to patients and provide more targeted treatment.

This discovery allows people who inherit genes that are susceptible to heart disease to be warned in childhood, so they can improve their diet and exercise more in advance, the report said.

The discovery of genetic defects in heart disease is one of the results of the Wellcome Foundation Case Control Consortium. The agency conducts the largest-ever genetic study of common diseases.

Nilesh Samani, a professor at the University of Leicester in the UK, said: "The genetic variations we are talking about here are not rare, but are very common in the population. Among white Europeans, there are four One to three quarters of people carry most of these variants." Researchers compared the genetic makeup of 2,900 heart disease patients with 4,600 healthy people and identified six genetic variants.
