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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SLC4A4. . Gene score misZ 3.144 (greater than the threshold 3.09). Trascript score misZ 4.3739 (greater than threshold 3.09). GenCC has associacion of gene with autosomal recessive proximal renal tubular acidosis.
BP4
Computational evidence support a benign effect (MetaRNN=0.117456704).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 11, 2022The c.200A>G (p.K67R) alteration is located in exon 3 (coding exon 2) of the SLC4A4 gene. This alteration results from a A to G substitution at nucleotide position 200, causing the lysine (K) at amino acid position 67 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
