Genes affected

SLC6A7 (HGNC:11054): (solute carrier family 6 member 7) This gene is a member of the gamma-aminobutyric acid (GABA) neurotransmitter gene family and encodes a high-affinity mammalian brain L-proline transporter protein. This transporter protein differs from other sodium-dependent plasma membrane carriers by its pharmacological specificity, kinetic properties, and ionic requirements. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.55).
• BP7: Synonymous conserved (PhyloP=0.978 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.757 is higher than 0.05.
