Iodine deficiency French, the term "crétin des Alpes" also became current, since the condition was observed in remote valleys of the Alps in particular. The word "cretin" appeared in English in 1779. While reporting recent progress towards overcoming iodine-deficiency disorders worldwide, "The Lancet" noted: "According to World Health Organization, in 2007, nearly 2 billion individuals had insufficient iodine intake, a third being of school age." A conclusion was made that the single most preventable cause of intellectual disability is that of iodine deficiency. There is preliminary evidence that iodine deficiency enhances the sensitivity of breast tissue to estrogen. In rats treated with
Acyl-CoA oxidase deficiency Acyl-CoA oxidase deficiency Acyl-CoA oxidase deficiency (ACOX1 deficiency) is a rare disorder that leads to significant damage and deterioration of nervous system functions (neurodegeneration). It is caused by pathogenic variants in "ACOX1", which codes for the production of an enzyme called peroxisomal straight-chain acyl-CoA oxidase (ACOX1). This specific enzyme is responsible for the breakdown of very long chain fatty acids (VLCFAs). Defective function of the ACOX1 enzyme prevents proper breakdown of these VLCFAs, leading to accumulation and interference with the nervous system. Acyl-CoA oxidase deficiency affects a person from birth, and most newborns affected with this condition will not survive
