Lathosterolosis

Lathosterolosis
Other namesSC5D Deficiency,[1] Sterol C5-desaturase deficiency.[2]
Lathosterol
SymptomsFacial dysmorphism, congenital malformations, failure to thrive, developmental delay, and liver illness.[2]
Usual onsetBirth.[2]
CausesSC5D mutations.[2]
Differential diagnosisSmith-Lemli-Opitz syndrome.[1]

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]
