Genes affected

SLC6A2 (HGNC:11048): (solute carrier family 6 member 2) This gene encodes a member of the sodium:neurotransmitter symporter family. This member is a multi-pass membrane protein, which is responsible for reuptake of norepinephrine into presynaptic nerve terminals and is a regulator of norepinephrine homeostasis. Mutations in this gene cause orthostatic intolerance, a syndrome characterized by lightheadedness, fatigue, altered mentation and syncope. Alternatively spliced transcript variants encoding different isoforms have been identified in this gene.[provided by RefSeq, Feb 2010]

The c.118A>T (p.N40Y) alteration is located in exon 1 (coding exon 1) of the SLC6A2 gene. This alteration results from a A to T substitution at nucleotide position 118, causing the asparagine (N) at amino acid position 40 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
