The NM_001045.6(SLC6A4):c.-220-1732C>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.338 (AC=51,358) in the gnomAD database across 152,060 control chromosomes, including 9,252 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.389. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

SLC6A4 (HGNC:11050): (solute carrier family 6 member 4) This gene encodes an integral membrane protein that transports the neurotransmitter serotonin from synaptic spaces into presynaptic neurons. The encoded protein terminates the action of serotonin and recycles it in a sodium-dependent manner. This protein is a target of psychomotor stimulants, such as amphetamines and cocaine, and is a member of the sodium:neurotransmitter symporter family. A repeat length polymorphism in the promoter of this gene has been shown to affect the rate of serotonin uptake. There have been conflicting results in the literature about the possible effect, if any, that this polymorphism may play in behavior and depression. [provided by RefSeq, May 2019]
