Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001008391.4(CCDC73):c.3212C>G(p.Thr1071Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000025 in 1,601,614 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T1071A) has been classified as Uncertain significance.

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.3212C>G (p.T1071R) alteration is located in exon 18 (coding exon 17) of the CCDC73 gene. This alteration results from a C to G substitution at nucleotide position 3212, causing the threonine (T) at amino acid position 1071 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
