Lathosterolosis is an inborn error of cholesterol biosynthesis caused by a deficiency of the enzyme 3-beta-hydroxysteroid-delta-5-desaturase. This leads to a flaw in the conversion of lathosterol to 7-dehydrocholesterol. Characteristics include facial dysmorphism, congenital malformations, failure to thrive, developmental delay, and liver illness. [2] Brunetti-Pierri et al. originally described Lathosterolosis in 2002. [3] [4] [5] [6]
