Genes affected

CCDC73 (HGNC:23261): (coiled-coil domain containing 73)

CCDC73 links:

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]

The c.3220A>C (p.K1074Q) alteration is located in exon 18 (coding exon 17) of the CCDC73 gene. This alteration results from a A to C substitution at nucleotide position 3220, causing the lysine (K) at amino acid position 1074 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
