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 Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
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=0.27224696).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2024The c.154G>T (p.D52Y) alteration is located in exon 1 (coding exon 1) of the SLC6A2 gene. This alteration results from a G to T substitution at nucleotide position 154, causing the aspartic acid (D) at amino acid position 52 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
