About
Patients with biochemically confirmed SLOS are being treated with cholesterol supplementation and antioxidant medication. They are carefully monitored with visits to clinic, laboratory testing including cholesterol and 7-dehydrocholesterol levels, vitamin levels, blood counts and liver and kidney function. On a serial basis, no more often than once a year, the patients undergo a series of tests under anesthesia, including electroretinogram (ERG), brainstem audiometry (ABR), and ophthalmologic exam under anesthesia to follow pigmentary retinopathy.
Full description
Smith-Lemli-Opitz Syndrome (SLOS) is an autosomal recessive disorder caused by a metabolic error in the final step of cholesterol biosynthesis, leading to cholesterol deficiency and accumulation of the cholesterol precursor, 7-dehydrocholesterol.Patients with SLOS display complex medical problems including growth failure, intellectual disability, behavioral disorders, progressive retinal dystrophy, hearing loss and photosensitivity. Dr Elias was one of the original geneticists who discovered the cause of this disorder in 1994, and ever since has been treating SLOS patients with cholesterol supplementation. In 2008, a second medication called AquADEKS, a mixture of vitamins and other compounds with antioxidant properties was added to the treatment regimen. AquADEKS has since been replaced with a comparable medication named DEKAS plus.The purpose of the DEKAS plus is to allow treatment with antioxidant medications in an effort to prevent retinal degeneration, hearing and skin problems associated with SLOS.
This protocol has been approved by the Colorado Multiple Institutional Review Board and supported by the Clinical Translational Research Center (CTRC) since 2001. The following updated information is available about the protocol:
