A common finding is that mouse models of SLOS show abnormal serotonergic development, which may be at least partially responsible for the autistic behaviours seen in SLOS. Mouse models have also been used to develop diagnostic techniques; multiple studies have examined biomarkers that result from the oxidation of 7DHC, such as DHCEO. It is likely that as animal models are improved, they will lead to many more discoveries in SLOS research. Eponym
It is named after David Weyhe Smith (1926–1981), an American pediatrician; Luc Lemli (1935–), a Belgian physician; and John Marius Opitz (1935–), a German-American physician. These are the researchers who first described the symptoms of SLOS. References

GeneReview/UW/NIH on Smith–Lemli–Opitz syndrome
The elevation of baseline triglyceride levels begins the cascade into other pathologies.The most common acute manifestation of hypertriglyceridemia is the occurrence of pancreatitis. Pancreatitis is caused by the premature activation of exocrine pancreatic enzymes. Secreted zymogens are cleaved to active trypsin and play a central role in digestion of food in the duodenum. If there is premature activation of trypsin within the pancreatic tissues, there is an induction of autodigestion of local tissue which leads to the initial presentation of pancreatitis. Autodigestion of local tissues also leads to disruptions in pancreatic microvascular tissue which can cause an ischemia-reperfusion event at the pancreatic level. There are other varying secondary causes of pancreatitis that can further contribute to the primary scenario of pancreatitis related to familial hypertriglyceridemia. Treatment
Treatment for familial hypertriglyceridemia should focus primarily on reducing serum triglyceride levels. If an individual has co-morbid conditions, ensuring that they are adequately addressed will aid in obtaining a more normal baseline lipid panel. Current guidelines suggest that when evaluating individuals with familial hypertriglyceridemia there should be special attention paid to their risk of developing cardiovascular disease in individuals with mild to moderate hypertriglyceridemia. Individuals with severe hypertriglyceridemia should be promptly evaluated for the possibility of developing pancreatitis. The initial treatment for severe hypertriglyceridemia consists of beginning an individual on fibrate therapy in an attempt to normalize triglyceride levels. Fibrates such as fenofibrate or gemfibrozil are considered first-line therapy for the disease. Adjunctive niacin therapy can be used for individuals who are unable to decrease triglyceride levels through fibrate monotherapy.
