Treacher Collins syndrome is a genetic disorder that affects the development of facial bones and tissues. It is caused by mutations in specific genes, leading to characteristic features such as underdeveloped cheekbones, a small jaw, and ear abnormalities. The severity of the condition can vary widely among individuals. People with Treacher Collins syndrome may also experience hearing loss and have difficulty with dental issues. While the syndrome is not life-threatening, individuals may require surgeries and other treatments to improve their appearance and function. Early intervention and support can help enhance quality of life for those affected.
