  • Title: [Smith-Lemli-Opitz syndrome; a special defect in cholesterol metabolism].
    Author: Aalfs CM, Hennekam RC, Wanders RJ, Jira PE, Pilon JW, Wijburg FA.
    Journal: Ned Tijdschr Geneeskd; 1996 Jul 13; 140(28):1463-6. PubMed ID: 8766772.
    Abstract:
    In a male neonate dysmaturity, microcephalia, a high nasal bridge, a long philtrum, broad dental ridges, schisis of the palatum molle, retrognathia, a small penis with a chorda, a small scrotum, bilateral inguinal hernia and bilateral syndactyly of the second and third toes were observed. The presence of the Smith-Lemli-Opitz (SLO) syndrome was suspected. By gas chromatography a severely decreased plasma cholesterol level (0.27 mmol/l) was found and an increased plasma 7-dehydrocholesterol level (0.24 mmol/l). The SLO syndrome is caused by a block in the cholesterol biosynthesis due to the autosomal recessive deficiency of 7-dehydrocholesterol reductase. The patient's condition improved with use of a cholesterol-enriched diet.
