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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 11, 2021 | The c.1184T>C (p.I395T) alteration is located in exon 12 (coding exon 12) of the IQGAP1 gene. This alteration results from a T to C substitution at nucleotide position 1184, causing the isoleucine (I) at amino acid position 395 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
