Genes affected
SLC4A8 (HGNC:11034): (solute carrier family 4 member 8) The protein encoded by this gene is a membrane protein that functions to transport sodium and bicarbonate ions across the cell membrane. The encoded protein is important for pH regulation in neurons. The activity of this protein can be inhibited by 4,4'-Di-isothiocyanatostilbene-2,2'-disulfonic acid (DIDS). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.2141C>T (p.T714M) alteration is located in exon 16 (coding exon 16) of the SLC4A8 gene. This alteration results from a C to T substitution at nucleotide position 2141, causing the threonine (T) at amino acid position 714 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
