Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_004174.4(SLC9A3):c.1814G>T(p.Arg605Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R605Q) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 34)
• Consequence: SLC9A3 NM_004174.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.52

Genes affected

SLC9A3 (HGNC:11073): (solute carrier family 9 member A3) The protein encoded by this gene is an epithelial brush border Na/H exchanger that uses an inward sodium ion gradient to expel acids from the cell. Defects in this gene are a cause of congenital secretory sodium diarrhea. Pseudogenes of this gene exist on chromosomes 10 and 22. [provided by RefSeq, Mar 2016]

SLC9A3-AS1 (HGNC:40550): (SLC9A3 antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.14785123).
