Genes affected

DRD2 (HGNC:3023): (dopamine receptor D2) This gene encodes the D2 subtype of the dopamine receptor. This G-protein coupled receptor inhibits adenylyl cyclase activity. A missense mutation in this gene causes myoclonus dystonia; other mutations have been associated with schizophrenia. Alternative splicing of this gene results in two transcript variants encoding different isoforms. A third variant has been described, but it has not been determined whether this form is normal or due to aberrant splicing. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.34).
• BP6: Variant 11-113416972-C-T is Benign according to our data. Variant chr11-113416972-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 238185.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=0.108 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0234 (3558/152318) while in subpopulation SAS AF = 0.0348 (168/4822). AF 95% confidence interval is 0.0334. There are 66 homozygotes in GnomAd4. There are 1732 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High AC in GnomAd4 at 3558 AD gene.
