Genes affected

IQGAP1 (HGNC:6110): (IQ motif containing GTPase activating protein 1) This gene encodes a member of the IQGAP family. The protein contains four IQ domains, one calponin homology domain, one Ras-GAP domain and one WW domain. It interacts with components of the cytoskeleton, with cell adhesion molecules, and with several signaling molecules to regulate cell morphology and motility. Expression of the protein is upregulated by gene amplification in two gastric cancer cell lines. [provided by RefSeq, Jul 2008]

Ambry Genetics

Nov 17, 2022

The c.1059T>G (p.D353E) alteration is located in exon 10 (coding exon 10) of the IQGAP1 gene. This alteration results from a T to G substitution at nucleotide position 1059, causing the aspartic acid (D) at amino acid position 353 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
