There is no cure for SLOS or other inherited diseases related to cholesterol production or storage. The data gained in this study may help researchers find ways to measure how well future treatments work. Objective: To learn more about SLOS and related disorders and how these diseases affect participants and relatives. Eligibility: People of any age who have or are suspected to have SLOS or another inherited disease related to cholesterol production or storage. Relatives are also needed. Design: Participants will be screened with a medical record review. Participants will have visits every 6 to 12 months. They will have a physical exam. They will fill out a survey about their medical and behavioral history. They may have an eye exam. They may have a neurodevelopmental assessment. They may have a hearing test. Their outer and middle ears may be examined. Their ability to speak, understand speech, eat, and swallow may be assessed. They may get X-rays while they chew and swallow. Their functional ability and needs for adaptive devices or braces may be assessed. They may have a lumbar puncture. Photographs may be taken of their face and body.
