Genes affected

AURKB (HGNC:11390): (aurora kinase B) This gene encodes a member of the aurora kinase subfamily of serine/threonine kinases. The genes encoding the other two members of this subfamily are located on chromosomes 19 and 20. These kinases participate in the regulation of alignment and segregation of chromosomes during mitosis and meiosis through association with microtubules. A pseudogene of this gene is located on chromosome 8. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2015]

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PVS1: Start lost variant, no pathogenic variants between lost start and next in-frame start position. Next in-frame start position is after 17 codons. Genomic position: 8207605. Lost 0.054 part of the original CDS.
• PM2: Very rare variant in population databases, with high coverage
