Genes affected

SLC6A3 (HGNC:11049): (solute carrier family 6 member 3) This gene encodes a dopamine transporter which is a member of the sodium- and chloride-dependent neurotransmitter transporter family. The 3' UTR of this gene contains a 40 bp tandem repeat, referred to as a variable number tandem repeat or VNTR, which can be present in 3 to 11 copies. Variation in the number of repeats is associated with idiopathic epilepsy, attention-deficit hyperactivity disorder, dependence on alcohol and cocaine, susceptibility to Parkinson disease and protection against nicotine dependence.[provided by RefSeq, Nov 2009]

ACMG classification

Verdict is Benign. Variant got -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.46).
• BP6: Variant 5-1432571-G-A is Benign according to our data. Variant chr5-1432571-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 470639.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr5-1432571-G-A is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=3.26 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00378 (576/152372) while in subpopulation NFE AF= 0.00328 (223/68026). AF 95% confidence interval is 0.00293. There are 6 homozygotes in gnomad4. There are 368 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 6 AR gene
