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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0196 (2980/152210) while in subpopulation NFE AF= 0.0277 (1881/68018). AF 95% confidence interval is 0.0266. There are 41 homozygotes in gnomad4. There are 1498 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd at 2980 AD gene.
