Genes affected

GIT2 (HGNC:4273): (GIT ArfGAP 2) This gene encodes a member of the GIT protein family, which interact with G protein-coupled receptor kinases and possess ADP-ribosylation factor (ARF) GTPase-activating protein (GAP) activity. GIT proteins traffic between cytoplasmic complexes, focal adhesions, and the cell periphery, and interact with Pak interacting exchange factor beta (PIX) to form large oligomeric complexes that transiently recruit other proteins. GIT proteins regulate cytoskeletal dynamics and participate in receptor internalization and membrane trafficking. This gene has been shown to repress lamellipodial extension and focal adhesion turnover, and is thought to regulate cell motility. This gene undergoes extensive alternative splicing to generate multiple isoforms, but the full-length nature of some of these variants has not been determined. The various isoforms have functional differences, with respect to ARF GAP activity and to G protein-coupled receptor kinase 2 binding. [provided by RefSeq, Sep 2008]

TCHP (HGNC:28135): (trichoplein keratin filament binding) Involved in apoptotic process; negative regulation of cell growth; and negative regulation of cilium assembly. Located in several cellular components, including apical cortex; cytoskeleton; and mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

The c.2158G>C (p.G720R) alteration is located in exon 20 (coding exon 20) of the GIT2 gene. This alteration results from a G to C substitution at nucleotide position 2158, causing the glycine (G) at amino acid position 720 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
