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.958G>A (p.A320T) alteration is located in exon 13 (coding exon 13) of the MSI2 gene. This alteration results from a G to A substitution at nucleotide position 958, causing the alanine (A) at amino acid position 320 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
