Genes affected

EIF3M (HGNC:24460): (eukaryotic translation initiation factor 3 subunit M) This gene encodes a protein that is part of the eurkaryotic translation initiation factor 3 complete (eIF-3) required for protein synthesis. Elevated levels of the encoded protein are present in cancer cell lines. Inactivation of the encoded protein has been shown to interfere with translation of herpes virus mRNAs by preventing the association of mRNAs with the ribosomes. A pseudogene of this gene is located on the X chromosome. [provided by RefSeq, Dec 2011]

EIF3M (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.42049015).

The c.790G>C (p.D264H) alteration is located in exon 8 (coding exon 8) of the EIF3M gene. This alteration results from a G to C substitution at nucleotide position 790, causing the aspartic acid (D) at amino acid position 264 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
