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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.538C>G (p.P180A) alteration is located in exon 4 (coding exon 4) of the SLC6A7 gene. This alteration results from a C to G substitution at nucleotide position 538, causing the proline (P) at amino acid position 180 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
