Genes affected

SLC29A4 (HGNC:23097): (solute carrier family 29 member 4) This gene encodes a member of the SLC29A/ENT transporter protein family. The encoded membrane protein catalyzes the reuptake of monoamines into presynaptic neurons, thus determining the intensity and duration of monoamine neural signaling. It has been shown to transport several compounds, including serotonin, dopamine, and the neurotoxin 1-methyl-4-phenylpyridinium. Alternative splicing results in multiple transcript variants.

The c.448A>G (p.I150V) alteration is located in exon 5 (coding exon 4) of the SLC29A4 gene. This alteration results from a A to G substitution at nucleotide position 448, causing the isoleucine (I) at amino acid position 150 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
