Rare genetic syndromes are conditions caused by abnormalities in an individual's DNA. These syndromes can lead to a variety of health issues, including physical, developmental, and cognitive challenges. Because they are uncommon, many healthcare providers may not be familiar with them, making diagnosis and treatment more difficult. Examples of rare genetic syndromes include Williams syndrome, characterized by cardiovascular issues and unique personality traits, and Angelman syndrome, which affects neurological development and causes severe speech impairment. Research into these syndromes is ongoing, aiming to improve understanding and treatment options for affected individuals and their families.
