Genes affected

RAC1 (HGNC:9801): (Rac family small GTPase 1) The protein encoded by this gene is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RAC1. . Gene score misZ 3.1347 (greater than the threshold 3.09). Trascript score misZ 3.9366 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 48.
• PP5: Variant 7-6391945-T-A is Pathogenic according to our data. Variant chr7-6391945-T-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 3235757.Status of the report is criteria_provided_single_submitter, 1 stars.
