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]

The c.695T>A (p.I232N) alteration is located in exon 5 (coding exon 5) of the SLC6A7 gene. This alteration results from a T to A substitution at nucleotide position 695, causing the isoleucine (I) at amino acid position 232 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
