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]

Dec 06, 2023

The c.707G>T (p.R236L) alteration is located in exon 6 (coding exon 6) of the SLC4A8 gene. This alteration results from a G to T substitution at nucleotide position 707, causing the arginine (R) at amino acid position 236 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
