Genes affected

RGS9 (HGNC:10004): (regulator of G protein signaling 9) This gene encodes a member of the RGS family of GTPase activating proteins that function in various signaling pathways by accelerating the deactivation of G proteins. This protein is anchored to photoreceptor membranes in retinal cells and deactivates G proteins in the rod and cone phototransduction cascades. Mutations in this gene result in bradyopsia. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004187554).
• BP6: Variant 17-65225096-G-A is Benign according to our data. Variant chr17-65225096-G-A is described in ClinVar as [Benign]. Clinvar id is 94379.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr17-65225096-G-A is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0114 (1735/152086) while in subpopulation NFE AF= 0.0195 (1327/67948). AF 95% confidence interval is 0.0187. There are 15 homozygotes in gnomad4. There are 791 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 15 AR gene
