Genes affected
EIF4G3 (HGNC:3298): (eukaryotic translation initiation factor 4 gamma 3) The protein encoded by this gene is thought to be part of the eIF4F protein complex, which is involved in mRNA cap recognition and transport of mRNAs to the ribosome. Interestingly, a microRNA (miR-520c-3p) has been found that negatively regulates synthesis of the encoded protein, and this leads to a global decrease in protein translation and cell proliferation. Therefore, this protein is a key component of the anti-tumor activity of miR-520c-3p. [provided by RefSeq, May 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.4337C>T (p.P1446L) alteration is located in exon 32 (coding exon 28) of the EIF4G3 gene. This alteration results from a C to T substitution at nucleotide position 4337, causing the proline (P) at amino acid position 1446 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
