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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.530A>C (p.K177T) alteration is located in exon 8 (coding exon 8) of the MSI1 gene. This alteration results from a A to C substitution at nucleotide position 530, causing the lysine (K) at amino acid position 177 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
