Genes affected

SLC18A2 (HGNC:10935): (solute carrier family 18 member A2) This gene encodes an transmembrane protein that functions as an ATP-dependent transporter of monoamines, such as dopamine, norepinephrine, serotonin, and histamine. This protein transports amine neurotransmitters into synaptic vesicles. Polymorphisms in this gene may be associated with schizophrenia, bipolar disorder, and other neurological/psychiatric ailments.

SLC18A2-AS1 (HGNC:55843): (SLC18A2 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.49).
• BP6: Variant 10-117241720-C-T is Benign according to our data. Variant chr10-117241720-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 747914.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.225 with no splicing effect.
• BS1: Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.00014 (204/1452478) while in subpopulation MID AF = 0.00859 (44/5124). AF 95% confidence interval is 0.00657. There are 4 homozygotes in GnomAdExome4. There are 117 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 4 Unknown,AR gene
