Description

8-Dehydrocholesterol (8-DHC) elevated concentration is one of the diagnostic biochemical hallmarks of classical Smith-Lemli-Opitz syndrome (SLOS) . Plasma 8-DHC could be only marginally elevated. ( PMID: 16435228) Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive condition caused by a defect in cholesterol synthesis (caused by a deficit of 3beta-hydroxysterol-Delta7 reductase). Affected children often have malformations and mental retardation. Autistic behaviors also are evident. In children, the baseline cholesterol, 8-DHC levels, and cholesterol levels following supplementation does not correlate with the presence or severity of autistic symptoms. PMID: 16761297 Accumulation of 8-dehydrocholesterol in Amniotic fluid is diagnostic for SLOS.
