Genes affected

SLC4A4 (HGNC:11030): (solute carrier family 4 member 4) This gene encodes a sodium bicarbonate cotransporter (NBC) involved in the regulation of bicarbonate secretion and absorption and intracellular pH. Mutations in this gene are associated with proximal renal tubular acidosis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.194C>T (p.S65F) alteration is located in exon 3 (coding exon 2) of the SLC4A4 gene. This alteration results from a C to T substitution at nucleotide position 194, causing the serine (S) at amino acid position 65 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
