• NM_003058.4:c.808T>C

Variant summary

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

The NM_003058.4(SLC22A2):​c.808T>C​(p.Ser270Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 12/21 in silico tools predict 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. S270A) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: SLC22A2 NM_003058.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.50

Genes affected

SLC22A2 (HGNC:10966): (solute carrier family 22 member 2) Polyspecific organic cation transporters in the liver, kidney, intestine, and other organs are critical for elimination of many endogenous small organic cations as well as a wide array of drugs and environmental toxins. This gene is one of three similar cation transporter genes located in a cluster on chromosome 6. The encoded protein contains twelve putative transmembrane domains and is a plasma integral membrane protein. It is found primarily in the kidney, where it may mediate the first step in cation reabsorption. [provided by RefSeq, Jul 2008]
