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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SLC4A8. . Gene score misZ 4.0551 (greater than the threshold 3.09). Trascript score misZ 4.6916 (greater than threshold 3.09). GenCC has associacion of gene with schizophrenia.
BP4
Computational evidence support a benign effect (MetaRNN=0.33488256).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.556A>G (p.S186G) alteration is located in exon 5 (coding exon 5) of the SLC4A8 gene. This alteration results from a A to G substitution at nucleotide position 556, causing the serine (S) at amino acid position 186 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
