Period 5 element dimethyl telluride, (CH)Te, a gas with a garlic-like odor which is exhaled in the breath of victims of tellurium toxicity or exposure. Iodine is the heaviest essential element utilized widely by life in biological functions (only tungsten, employed in enzymes by a few species of bacteria, is heavier). Iodine's rarity in many soils, due to initial low abundance as a crust-element, and also leaching of soluble iodide by rainwater, has led to many deficiency problems in land animals and inland human populations. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. Iodine is
ZC4H2 deficiency neurological manifestations. These can include: To date, there is no cure or effective treatment for this condition. Current approach is limited to supportive therapies and interventions. ZC4H2 deficiency ZC4H2 (Zinc finger C4H2-type) is a protein-coding gene located on the X-chromosome. This gene encodes a protein which is a member of the so-called zinc finger domain-containing protein family. There is currently very limited understanding about the ZC4H2 gene and its protein function. Any pathogenic variant of ZC4H2 which is associated with a clinical phenotype is referred to as "ZC4H2 Deficiency". The limited research published to date indicates that ZC4H2 is expressed
