The NM_198437.3(AURKA):c.91T>G (p.Phe31Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene AURKA is a tumor suppressor gene (CancerMine: 4 TSG, 51 oncogene, 8 driver citations). The gene AURKA is a known oncogene (CancerMine: 4 TSG, 51 oncogene, 8 driver citations). The gene AURKA is a cancer driver gene (CancerMine: 4 TSG, 51 oncogene, 8 driver citations). The variant allele was found at a cumulative frequency of 0.0000062 (AC=10) in the gnomAD database across 1,613,946 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000147. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.F31I: Benign (ClinVar VariationId 6642, 2 stars)

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]

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 0 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Very rare in gnomAD (popmax AF <0.01%) — O3 supporting; GnomAD effective popmax AF = 0.000015 — very rare (O3 supporting [+1])
	B3Computational evidence does not support deleterious effect		Computational evidence does not support a deleterious effect; Missense variant — primary computational scorer does not support an oncogenic/deleterious effect; supports B3
