(AURKA Phe31Ile)

Short summary

The AURKA (STK15) 91T->A variant is preferentially amplified and linked to the degree of aneuploidy in colon tumors. The variant is a low-penetrance cancer susceptibility allele associated with multiple cancer types.

Ewart-Toland A, Briassouli P, de Koning JP, Mao JH, Yuan J, Chan F, MacCarthy-Morrogh L, Ponder BA, Nagase H, Burn J, Ball S, Almeida M, Linardopoulos S, Balmain A. Identification of Stk6/STK15 as a candidate low-penetrance tumor-susceptibility gene in mouse and human. Nat Genet. 2003 Aug;34(4):403-12. PubMed PMID: 12881723.

Based on mouse studies, AURKA (STK15) was identified as a candidate skin tumor susceptibility gene. STK15 is frequently amplified in human colon cancers and other tumor types. The authors identified the STK15 91T->A variant and showed “statistically significant allele-specific amplification of the 91A allele (P = 0.018, chi squared test), providing additional evidence for the role of this allele in human cancer”. Individuals with even one copy of the 91A allele develop tumors with a higher degree of aneuploidy than homozygous 91T individuals.

Aurora-A/STK15 T+91A is a general low penetrance cancer susceptibility gene: a meta-analysis of multiple cancer types. Carcinogenesis. 2005 Aug;26(8):1368-73. Epub 2005 Mar 31. PubMed PMID: 15802297.

Meta-analysis confirmed that the 91A polymorphism is a low-penetrance cancer susceptibility allele in several cancer types, with greater risk for the 91A homozygotes. When the results were combined in a meta-analysis, the authors “found an OR of 1.4 for the T+91A homozygotes (95% CI of 1.22—1.59, P-value < 0.001)” and a “modest but significant increase in risk in the T+91A heterozygotes (OR = 1.10, 95% CI 1.03—1.18, P-value = 0.006)”.
