Genes affected

EWSR1 (HGNC:3508): (EWS RNA binding protein 1) This gene encodes a multifunctional protein that is involved in various cellular processes, including gene expression, cell signaling, and RNA processing and transport. The protein includes an N-terminal transcriptional activation domain and a C-terminal RNA-binding domain. Chromosomal translocations between this gene and various genes encoding transcription factors result in the production of chimeric proteins that are involved in tumorigenesis. These chimeric proteins usually consist of the N-terminal transcriptional activation domain of this protein fused to the C-terminal DNA-binding domain of the transcription factor protein. Mutations in this gene, specifically a t(11;22)(q24;q12) translocation, are known to cause Ewing sarcoma as well as neuroectodermal and various other tumors. Alternative splicing of this gene results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 1 and 14. [provided by RefSeq, Jul 2009]

RHBDD3 (HGNC:1308): (rhomboid domain containing 3) Predicted to enable serine-type endopeptidase activity. Predicted to be involved in proteolysis. Predicted to act upstream of or within several processes, including liver development; negative regulation of natural killer cell activation; and positive regulation of protein catabolic process. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]
