What genetic condition is associated with a high-pitched, cat-like cry?

The condition associated with a high-pitched, cat-like cry is Cri du Chat Syndrome. This genetic disorder is caused by a deletion of a portion of chromosome 5. One of the hallmark features of Cri du Chat Syndrome is the distinct cry of affected infants, which resembles the mewing of a cat. This sound results from the structural abnormalities of the larynx and vocal cords that are characteristic of the syndrome.

Beyond the unique cry, children with Cri du Chat often exhibit developmental delays and various physical features, such as a smaller head size and distinctive facial features. These characteristics help in identifying the syndrome early in life. Understanding the specific cry associated with Cri du Chat is important for early diagnosis and intervention, making it a key aspect of the disorder's clinical presentation.
