Abstract
Over the past decade, 11 human genes belonging to the solute linked carrier (SLC) 26 family of transporters, have been identified. The SLC26 proteins, which include SAT-1, DTDST, DRA / CLD, pendrin, prestin, PAT-1 / CFEX and Tat-1, are structurally related and have been shown to transport one or more of the following substrates: sulfate, chloride, bicarbonate, iodide, oxalate, formate, hydroxyl or fructose. Special interest has focused on four members of the SLC26 family that are associated with distinct recessive diseases: (i) Mutations in SLC26A2 lead to four different chondrodysplasias (diastrophic dysplasia, atelosteogenesis type II, achondrogenesis type IB and multiple epiphyseal dysplasia); (ii) SLC26A3 is associated with congenital chloride diarrhea; (iii) SLC26A4 is associated with Pendred syndrome and non-syndromic deafness, DFNB4; and (iv) SLC26A5 is defective in non-syndromic hearing impairment. This review article summarizes current information on the pathophysiological consequences of mutations in the human SLC26A2 to A5 genes.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
