Genes affected
ARHGAP24 (HGNC:25361): (Rho GTPase activating protein 24) This gene encodes a Rho-GTPase activating protein, which is specific for the small GTPase family member Rac. Binding of the encoded protein by filamin A targets it to sites of membrane protrusion, where it antognizes Rac. This results in suppression of lamellae formation and promotion of retraction to regulate cell polarity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.164A>T (p.D55V) alteration is located in exon 2 (coding exon 1) of the ARHGAP24 gene. This alteration results from a A to T substitution at nucleotide position 164, causing the aspartic acid (D) at amino acid position 55 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 55 of the ARHGAP24 protein (p.Asp55Val). This variant is present in population databases (rs139936589, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with ARHGAP24-related conditions. ClinVar contains an entry for this variant (Variation ID: 2355844). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
