Genes affected

SLC22A8 (HGNC:10972): (solute carrier family 22 member 8) This gene encodes a protein involved in the sodium-independent transport and excretion of organic anions, some of which are potentially toxic. The encoded protein is an integral membrane protein and appears to be localized to the basolateral membrane of the kidney. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene. [provided by RefSeq, May 2010]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.060691833).

The c.555T>G (p.F185L) alteration is located in exon 4 (coding exon 3) of the SLC22A8 gene. This alteration results from a T to G substitution at nucleotide position 555, causing the phenylalanine (F) at amino acid position 185 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
