To establish if they are associated with an increased malignant melanoma (MM) risk we did an association study based on genotyping 471 patients with MM and 1,2 10 random control subjects from the same Polish population. We found a significantly increased frequency of the A148T variant among patients with MM (7.0%) in comparison with the general population (2.9%). The incidence of the A148T variant remained greater in both unselected and familial melanoma subgroups. A statistically significant positive association was seen for unselected MM (odds ratio, 2.529; P = 0.0003), especially in patients diagnosed under 50 years of age (odds ratio, 3.4; P = 0.0002). The A148T carrier population (heterozygous G/A alleles) was more likely to have a relative with malignancy compared with the noncarrier population (57% versus 36%, respectively; P = 0.03). Further examination of the CDKN2A promoter sequence done in 20 melanoma patients with the A148T change (heterozygous G/A alleles) and 20 patients with MM without this alteration identified it was in linkage disequilibrium with a polymorphism in the promoter region at position P-493. We found no statistically significant overrepresentation of the Nt500c>g and the Nt540c>t polymorphisms in the Polish melanoma population. In conclusion, the A148T variant of the CDKN2A gene seems to be associated with an increased risk of development of MM. Additional studies are required to confirm whether this particular change is associated with increased risk of other nonmelanoma malignancies.]]> Thu 25 Jul 2013 09:09:40 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:8124 Sat 24 Mar 2018 08:40:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18200 Sat 24 Mar 2018 08:04:51 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4808 Sat 24 Mar 2018 07:20:42 AEDT ]]>
