What is the average life span of a person with holoprosencephaly?

Answer 1

My sister had this and she died at age 7. They usually die when they're born though.

Answer 2

The life span of individuals with holoprosencephaly can vary based on the severity of their condition and associated health complications. Some individuals with milder forms of holoprosencephaly may live into adulthood with appropriate medical care, while those with more severe forms may have a shorter life expectancy, often dying in infancy or childhood. It is important for individuals with holoprosencephaly to receive interdisciplinary care to manage their medical needs and support their quality of life.
