Mutations in the ABCA12 gene cause harlequin ichthyosis. The ABCA12 gene provides instructions for making a protein that is essential for the normal development of skin cells. This protein plays a major role in the transport of fats (lipids) in the outermost layer of skin (the epidermis).
Uses of Boron. 1  Much boron is made into sodium tetraborate which is used to insulate fiberglass. 2  It is also used in many cleaning products-detergents and bleaches. 3  Most boron is used to produce glass and ceramics. It is also used in many cleaning products-detergents and bleaches. 2  Most boron is used to produce glass and ceramics. 3  Borosilicate glass has a fantastic resistance to thermal shock (sudden changes in temperature which causes glass to break).
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.
