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]

The c.1294A>G (p.I432V) alteration is located in exon 14 (coding exon 13) of the SLC18A1 gene. This alteration results from a A to G substitution at nucleotide position 1294, causing the isoleucine (I) at amino acid position 432 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
