Genes affected
SLC9A1 (HGNC:11071): (solute carrier family 9 member A1) This gene encodes a Na+/H+ antiporter that is a member of the solute carrier family 9. The encoded protein is a plasma membrane transporter that is expressed in the kidney and intestine. This protein plays a central role in regulating pH homeostasis, cell migration and cell volume. This protein may also be involved in tumor growth. [provided by RefSeq, Sep 2011]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 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), SLC9A1. . Gene score misZ 3.5504 (greater than the threshold 3.09). Trascript score misZ 4.6807 (greater than threshold 3.09). GenCC has associacion of gene with Lichtenstein-Knorr syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.113726705).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 07, 2024The c.2302G>A (p.E768K) alteration is located in exon 12 (coding exon 12) of the SLC9A1 gene. This alteration results from a G to A substitution at nucleotide position 2302, causing the glutamic acid (E) at amino acid position 768 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
