Genes affected

SLC18A1 (HGNC:10934): (solute carrier family 18 member A1) The vesicular monoamine transporter acts to accumulate cytosolic monoamines into vesicles, using the proton gradient maintained across the vesicular membrane. Its proper function is essential to the correct activity of the monoaminergic systems that have been implicated in several human neuropsychiatric disorders. The transporter is a site of action of important drugs, including reserpine and tetrabenazine (Peter et al., 1993 [PubMed 7905859]). See also SLC18A2 (MIM 193001).[supplied by OMIM, Mar 2008]

Ambry Genetics

Dec 14, 2021

The c.1355T>G (p.V452G) alteration is located in exon 15 (coding exon 14) of the SLC18A1 gene. This alteration results from a T to G substitution at nucleotide position 1355, causing the valine (V) at amino acid position 452 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
