Genes affected

G3BP1 (HGNC:30292): (G3BP stress granule assembly factor 1) This gene encodes one of the DNA-unwinding enzymes which prefers partially unwound 3'-tailed substrates and can also unwind partial RNA/DNA and RNA/RNA duplexes in an ATP-dependent fashion. This enzyme is a member of the heterogeneous nuclear RNA-binding proteins and is also an element of the Ras signal transduction pathway. It binds specifically to the Ras-GTPase-activating protein by associating with its SH3 domain. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008]

The c.455A>T (p.E152V) alteration is located in exon 6 (coding exon 5) of the G3BP1 gene. This alteration results from a A to T substitution at nucleotide position 455, causing the glutamic acid (E) at amino acid position 152 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
