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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SLC6A2. . Gene score misZ 2.0193 (greater than the threshold 3.09). Trascript score misZ 3.3305 (greater than threshold 3.09). GenCC has associacion of gene with postural orthostatic tachycardia syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.2834496).
BS2
High AC in GnomAdExome4 at 6 AD gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.11C>A (p.A4E) alteration is located in exon 1 (coding exon 1) of the SLC6A2 gene. This alteration results from a C to A substitution at nucleotide position 11, causing the alanine (A) at amino acid position 4 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
