Harlequin Ichthyosis Causes. The harlequin ichthyosis is known to be genetic in nature. The ABC 12 gene, which directs the protein production that is necessary to have a normal skin growth, is being mutated which leads to this severe skin disorder. It is a gene that is responsible for the transportation of lipid.
Boron (IPA: /ËbÉËrÉn/) is a chemical element with atomic number 5 and the chemical symbol B. A trivalent compound containing boron occurs abundantly in the ore borax. Boron is never found free in nature, and is a non-metal. Several allotropes of boron exist; amorphous boron is a brown powder, though crystalline boron is black, hard (9.3 on Mohs' scale), and a weak conductor at room temperature.
Boron compounds are also used as fertilizers in agriculture, and in sodium perborate bleaches. In minor uses, boron is an important dopant for semiconductors, and boron-containing reagents are used as intermediates in the synthesis of organic fine chemicals.A few boron-containing organic pharmaceuticals are used, or are in study.atural boron is composed of two stable isotopes, one of which (boron-10) has a number of uses as a neutron-capturing agent. In biology, borates have low toxicity in mammals (similar to table salt), but are more toxic to arthropods and are used as insecticides.
