Genes affected

EIF4ENIF1 (HGNC:16687): (eukaryotic translation initiation factor 4E nuclear import factor 1) The protein encoded by this gene is a nucleocytoplasmic shuttle protein for the translation initiation factor eIF4E. This shuttle protein interacts with the importin alpha-beta complex to mediate nuclear import of eIF4E. It is predominantly cytoplasmic; its own nuclear import is regulated by a nuclear localization signal and nuclear export signals. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2009]

EIF4ENIF1 links:

DRG1 (HGNC:3029): (developmentally regulated GTP binding protein 1) Enables several functions, including GTPase activity; identical protein binding activity; and potassium ion binding activity. Involved in positive regulation of microtubule polymerization and regulation of mitotic spindle assembly. Located in cytosol and nuclear body. Part of polysome.

The c.2312T>C (p.L771P) alteration is located in exon 17 (coding exon 16) of the EIF4ENIF1 gene. This alteration results from a T to C substitution at nucleotide position 2312, causing the leucine (L) at amino acid position 771 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
