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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.640C>T (p.R214C) 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 640, causing the arginine (R) at amino acid position 214 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
