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]

Ambry Genetics

Oct 26, 2021

The c.649C>T (p.L217F) alteration is located in exon 5 (coding exon 5) of the SLC6A7 gene. This alteration results from a C to T substitution at nucleotide position 649, causing the leucine (L) at amino acid position 217 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
