Genes affected
MSI1 (HGNC:7330): (musashi RNA binding protein 1) This gene encodes a protein containing two conserved tandem RNA recognition motifs. Similar proteins in other species function as RNA-binding proteins and play central roles in posttranscriptional gene regulation. Expression of this gene has been correlated with the grade of the malignancy and proliferative activity in gliomas and melanomas. A pseudogene for this gene is located on chromosome 11q13.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 03, 2023The c.578C>T (p.T193M) alteration is located in exon 9 (coding exon 9) of the MSI1 gene. This alteration results from a C to T substitution at nucleotide position 578, causing the threonine (T) at amino acid position 193 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
