Genes affected
SLC4A9 (HGNC:11035): (solute carrier family 4 member 9) The protein encoded by this gene is a membrane protein involved in anion exchange. Expression of this gene is mostly limited to the kidney. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2023The c.1918G>A (p.D640N) alteration is located in exon 14 (coding exon 14) of the SLC4A9 gene. This alteration results from a G to A substitution at nucleotide position 1918, causing the aspartic acid (D) at amino acid position 640 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
