Genes affected

ARHGAP4 (HGNC:674): (Rho GTPase activating protein 4) This gene encodes a member of the rhoGAP family of proteins which play a role in the regulation of small GTP-binding proteins belonging to the RAS superfamily. The protein encoded by the orthologous gene in rat is localized to the Golgi complex and can redistribute to microtubules. The rat protein stimulates the activity of some Rho GTPases in vitro. Genomic deletions of this gene and a neighboring gene have been found in patients with nephrogenic diabetes insipidus. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

The c.2945C>T (p.T982I) alteration is located in exon 23 (coding exon 23) of the ARHGAP4 gene. This alteration results from a C to T substitution at nucleotide position 2945, causing the threonine (T) at amino acid position 982 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
