The mystery of the dwarf village in China

Located in China's southwestern Sichuan province, Yangsi village has puzzled scientists for decades because 40% of the population is dwarf.

According to the village elders, their normal and happy lives were “destroyed one summer night in 1951” by a strange disease. The disease mainly affects children between the ages of 5 and 7, causing them to stop growing and remain at the same height for the rest of their lives. In addition to not growing taller, some patients suffer from various disabilities.

A 1985 census found some 119 similar cases in the village. The disease does not stop with the initial victims, it is passed on to the next generation. As of 2014, 36 of the village's 80 residents are dwarfs, the tallest being about 117 cm tall, the shortest 64 cm.

In January 2008, the health authorities of Zizhong County conducted X-ray examinations of the dwarfs in Yangsi Village. The X-rays showed bone abnormalities, reflecting stunted growth.

Dwarfism is short stature due to a medical or genetic condition. By definition, people with dwarfism are 147 cm (48 in) or shorter. The average height of a person with dwarfism is 122 cm (48 in).

There are many different medical conditions that cause dwarfism. The disorders generally fall into two broad categories:

- Disproportionate dwarfism causes the patient's body size to be disproportionate, with some parts being small and others being average or above average. These disorders cause disproportionate dwarfism and inhibit bone growth.

- Proportional dwarfism occurs when body parts are all relatively small, consistent with an average body size. The condition is present at birth or appears during childhood, limiting overall growth and development.

Scientists and experts visited Yangsi to study the water, soil, and food resources in the area. They examined the affected patients, hoping to find an explanation for the rare condition. In 1997, experts hypothesized that high levels of mercury were present in the soil of Yangsi, but they were unable to prove the hypothesis. As a result, the cause of the disease remains a mystery to this day.

Although the Chinese government did not deny the village’s existence, it closed the area to foreign visitors. Photographs of the locals circulated, along with some bizarre rumors. The village was officially recorded in 1951, but reports of dwarfs date back to 1911.

Recent studies have shown that later generations appear to be unaffected by the strange disease.
