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
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 9 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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.957
PP5
Variant 7-6387229-G-A is Pathogenic according to our data. Variant chr7-6387229-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 445280.Status of the report is criteria_provided_single_submitter, 1 stars.
