Genes affected
SLC7A2 (HGNC:11060): (solute carrier family 7 member 2) The protein encoded by this gene is a cationic amino acid transporter and a member of the APC (amino acid-polyamine-organocation) family of transporters. The encoded membrane protein is responsible for the cellular uptake of arginine, lysine and ornithine. Three transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2023The c.514A>G (p.R172G) alteration is located in exon 3 (coding exon 3) of the SLC7A2 gene. This alteration results from a A to G substitution at nucleotide position 514, causing the arginine (R) at amino acid position 172 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
