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.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0041761994).
• BA1: GnomAdExome4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.0509 is higher than 0.05.
