Genes affected

CENPE (HGNC:1856): (centromere protein E) Centrosome-associated protein E (CENPE) is a kinesin-like motor protein that accumulates in the G2 phase of the cell cycle. Unlike other centrosome-associated proteins, it is not present during interphase and first appears at the centromere region of chromosomes during prometaphase. This protein is required for stable spindle microtubule capture at kinetochores which is a necessary step in chromosome alignment during prometaphase. This protein also couples chromosome position to microtubule depolymerizing activity. Alternative splicing results in multiple transcript variants encoding distinct protein isoforms.

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.012%). Predicted Consequence/Location: Missense variant Functional studies provide supporting evidence of the variant having a damaging effect on the gene or gene product (PMID: 24748105). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.63; 3Cnet: 0.02). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000157497 /PMID: 24748105). The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 24748105). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

The D933N variant in the CENPE gene has been reported previously in the compound heterozygous state in two siblings with marked microcephaly, growth failure, developmental delay, and facial dysmorphism (Mirzaa et al., 2014). The D933N variant is observed in 10/34250 (0.029%) alleles from individuals of Latino background in large population cohorts, and no individuals are reported to be homozygous (Lek et al., 2016). The D933N variant is a semi-conservative amino acid substitution. Functional characterization of the D933N variant indicates that this variant induces mitotic spindle abnormalities and results in an increased frequency of polar chromosomes (Mirzaa et al., 2014). We interpret D933N as a likely pathogenic variant. -
