Genes affected

AURKA (HGNC:11393): (aurora kinase A) The protein encoded by this gene is a cell cycle-regulated kinase that appears to be involved in microtubule formation and/or stabilization at the spindle pole during chromosome segregation. The encoded protein is found at the centrosome in interphase cells and at the spindle poles in mitosis. This gene may play a role in tumor development and progression. A processed pseudogene of this gene has been found on chromosome 1, and an unprocessed pseudogene has been found on chromosome 10. Multiple transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a mutagenesis_site Decreases the interaction with phosphatase type 1 isoforms. (size 0) in uniprot entity AURKA_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 20-56370332-G-T is Pathogenic according to our data. Variant chr20-56370332-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 800338.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP4: Computational evidence support a benign effect (MetaRNN=0.07400298). . Strength limited to SUPPORTING due to the PP5.
