Position:

• chr1-27106019-T-G

Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2 PP2 PP5_Moderate

The NM_003047.5(SLC9A1):​c.1351A>C​(p.Ile451Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. I451I) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: SLC9A1 NM_003047.5 missense
• Clinical Significance: Likely pathogenic criteria provided, single submitter P:1
• Conservation: PhyloP100: 5.07

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

Verdict is Uncertain_significance. Variant got 5 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.
• PP5: Variant 1-27106019-T-G is Pathogenic according to our data. Variant chr1-27106019-T-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 520778.Status of the report is criteria_provided_single_submitter, 1 stars.
