Genes affected
RAB3GAP1 (HGNC:17063): (RAB3 GTPase activating protein catalytic subunit 1) This gene encodes the catalytic subunit of a Rab GTPase activating protein. The encoded protein forms a heterodimer with a non-catalytic subunit to specifically regulate the activity of members of the Rab3 subfamily of small G proteins. This protein mediates the hydrolysis of GTP bound Rab3 to the GDP bound form. Mutations in this gene are associated with Warburg micro syndrome. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Feb 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PP3
Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
BP6
Variant 2-135052329-A-G is Benign according to our data. Variant chr2-135052329-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 586392.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000657 (10/152208) while in subpopulation SAS AF= 0.00208 (10/4816). AF 95% confidence interval is 0.00113. There are 0 homozygotes in gnomad4. There are 8 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 4 AR gene
