Assessment of Children With Tic Onset in the Past 6 Months
https://clinicaltrials.gov/ct2/show/NCT01177774

Oct 22nd, 2021 - Up to 30% of all children will have a tic at some point. However, tics that last a whole year (or more) occur in only 3% of the population. Thus tic persistence may be more unusual than tic onset, yet almost no data exist on which people with recent-onset tics go on to be diagnosable with Tourette syndrome or chronic tic disorder, versus those whose tics are only transient. The overall goal of ...

Biochemical and Phenotypical Aspects of Smith-Lemli-Opitz Syndrome and Related Disorders of Cholesterol Metabolism
https://clinicaltrials.gov/ct2/show/NCT05047354

Oct 22nd, 2021 - Smith-Lemli-Opitz Syndrome (SLOS) is an autosomal recessive inborn error of metabolism secondary to cholesterol synthesis abnormalities that usually manifests with a combination of typical dysmorphology and intellectual disability.
