| Impact List | frameshift |
| Protein Effect | gain of function - predicted |
| Gene Variant Descriptions | CSF3R S783Kfs*6 indicates a shift in the reading frame starting at amino acid 783 and terminating 6 residues downstream causing a premature truncation of the 836 amino acid Csf3r protein (UniProt.org). S783Kfs*6 has not been characterized, but is predicted to lead to a gain of Csf3r protein function based on the effects of a similar frameshift mutation at S783 (PMID: 23656643). |
