Common Name:PDS
HGNC Symbol:SLC26A4
HGNC Description:solute carrier family 26 (anion exchanger), member 4
HGNC ID:8818
Chromosome:Chr.7(+): 107301080-107358254 GRCh37
OMIM Phenotype:Pendred syndrome; Deafness, autosomal recessive 4; Enlarger vestibular aqueduct
Nucleotide RefSeq:NM_000441
Protein RefSeq:NP_000432
Evidence:Substrate In Vitro Evidence: When expressed in Sf9 insect cells, PDS functioned as a chloride and iodide transporter, but did not transport sulfate (Scott DA, Wang R, Kreman TM, Sheffield VC, Karniski LP. The Pendred syndrome gene encodes a chloride-iodide transport protein. Nature Genet 21: 440-443, 1999. Substrate In Vivo Evidence: Pendred syndrome (PDS), the most common syndromal form of deafness, is an autosomal recessive disorder associated with developmental abnormalities of the cochlea, sensorineural hearing loss, and diffuse thyroid enlargement (goiter). Pendred syndrome has been linked to mutations in the SLC26A4 gene (Everett LA, Glaser B, Beck JC, Idol JR, Buchs A, Heyman M, Adawi F, Hazani E, Nassir E, Baxevanis AD, Sheffield VC, Green ED. Pendred syndrome is caused by mutations in a putative sulphate transporter gene (PDS). Nat Genet 17(4): 411-22, 1997). Targeted deletion of murine Slc26a4 results in profound deafness and variable deficits in vestibular function (Everett LA, Belyantseva IA, Noben-Trauth K, Cantos R, Chen A, Thakkar SI, Hoogstraten-Miller SL, Kachar B, Wu DK, Green ED. Targeted disruption of mouse Pds provides insight about the inner-ear defects encountered in Pendred syndrome. Hum Mol Genet 10:153-161, 2001). Tissue Distribution Evidence: By Northern blot, PDS was found to be expressed predominantly in the thyroid glands, with weaker signals in kidney and brain (Everett LA, Glaser B, Beck JC, Idol JR, Buchs A, Heyman M, Adawi F, Hazani E, Nassir E, Baxevanis AD, Sheffield VC, Green ED. Pendred syndrome is caused by mutations in a putative sulphate transporter gene (PDS). Nat Genet 17(4): 411-22, 1997).

GTEx Expression by Gene and Transcript

The heat map summarizes relative expression by tissue type at two levels of tissue detail, e.g., 'Brain' and 'Brain - Amygdala'. Choose among four calculated expression values, including mean and median RPKM values, and quantile normalized (QN) distributions of these values. (Note that differences between some distributions are subtle.) The coloring is relative to the mean of all displayed values. All values are log base 2. (See also PMT GTEx Expression Plotting.) Click on a transcript or tissue to resort the data.
