Genes affected

AURKC (HGNC:11391): (aurora kinase C) This gene encodes a member of the Aurora subfamily of serine/threonine protein kinases. The encoded protein is a chromosomal passenger protein that forms complexes with Aurora-B and inner centromere proteins and may play a role in organizing microtubules in relation to centrosome/spindle function during mitosis. This gene is overexpressed in several cancer cell lines, suggesting an involvement in oncogenic signal transduction. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.15913978 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.5, offset of -24, new splice context is: gtggcaggcttcacttccAGggt. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 19-57233458-A-G is Pathogenic according to our data. Variant chr19-57233458-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 66088.Status of the report is no_assertion_criteria_provided, 0 stars.
