Genes affected

CEP57 (HGNC:30794): (centrosomal protein 57) This gene encodes a cytoplasmic protein called Translokin. This protein localizes to the centrosome and has a function in microtubular stabilization. The N-terminal half of this protein is required for its centrosome localization and for its multimerization, and the C-terminal half is required for nucleating, bundling and anchoring microtubules to the centrosomes. This protein specifically interacts with fibroblast growth factor 2 (FGF2), sorting nexin 6, Ran-binding protein M and the kinesins KIF3A and KIF3B, and thus mediates the nuclear translocation and mitogenic activity of the FGF2. It also interacts with cyclin D1 and controls nucleocytoplasmic distribution of the cyclin D1 in quiescent cells. This protein is crucial for maintaining correct chromosomal number during cell division. Mutations in this gene cause mosaic variegated aneuploidy syndrome, a rare autosomal recessive disorder. Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Aug 2011]

The CEP57 p.Gln102His variant was identified in the literature in 1 of 96 Italian patients with gastric or lobular breast cancers (Tedaldi_2019_PMID:31514334). The variant was identified in dbSNP (ID: rs117321017) and ClinVar (classified as benign by Invitae), but was not identified in LOVD 3.0 or Cosmic. The variant was identified in control databases in 1635 of 282426 chromosomes (12 homozygous) at a frequency of 0.005789 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: European (non-Finnish) in 1135 of 128908 chromosomes (freq: 0.008805), Other in 53 of 7198 chromosomes (freq: 0.007363), European (Finnish) in 167 of 25120 chromosomes (freq: 0.006648), Ashkenazi Jewish in 62 of 10366 chromosomes (freq: 0.005981), Latino in 104 of 35428 chromosomes (freq: 0.002936), South Asian in 76 of 30602 chromosomes (freq: 0.002483) and African in 38 of 24856 chromosomes (freq: 0.001529), but was not observed in the East Asian population. The p.Gln102 residue is conserved in mammals but not in more distantly related organisms however four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
