Genes affected

MSI2 (HGNC:18585): (musashi RNA binding protein 2) This gene encodes an RNA-binding protein that is a member of the Musashi protein family. The encoded protein is transcriptional regulator that targets genes involved in development and cell cycle regulation. Mutations in this gene are associated with poor prognosis in certain types of cancers. This gene has also been shown to be rearranged in certain cancer cells. [provided by RefSeq, Apr 2016]

The c.931G>A (p.G311S) alteration is located in exon 12 (coding exon 12) of the MSI2 gene. This alteration results from a G to A substitution at nucleotide position 931, causing the glycine (G) at amino acid position 311 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
