Three mutations in BRCA1 (5382insC, C61G and 4153delA) are common in Poland and account for the majority of mutations identified to date in Polish breast and breast-ovarian cancer families. It is not known, however, to what extent these 3 founder mutations account for all of the BRCA mutations distributed throughout the country. This question has important(More)
The population frequencies of the CDKN2A variants remain undetermined. In Poland there are three common variants of CDKN2A: an alanine to threonine substitution (A148T), Nt500c>g and Nt540c>t, which have been detected in other populations. To establish if they are associated with an increased malignant melanoma (MM) risk we did an association study based on(More)
BACKGROUND A common missense variant of the CDKN2A gene (A148T) predisposes to malignant melanoma in Poland. An association between malignant melanoma and breast cancer has been reported in several families with CDKN2A mutations, OBJECTIVE To determine whether this variant also predisposes to breast cancer. METHODS Genotyping was undertaken in 4209(More)
There is increasing evidence that hereditary factors play a greater role in ovarian cancer than in any of the other common cancers of adulthood. This is attributable, to a large extent, to a high frequency of mutations in the BRCA1 or BRCA2 genes. In Poland, 3 common founder mutations in BRCA1 account for the majority of families with identified BRCA(More)

Germline mutations in the DNA mismatch repair genes MSH2 and MLH1 account for a significant proportion of hereditary non-polyposis colorectal cancer (HNPCC) families. One approach by which development of an efficient DNA-testing procedure can be implemented is to describe the nature and frequency of common mutations in particular ethnic groups. Two hundred(More)
The E318K mutation in the MITF gene has been associated with a high risk of melanoma, renal cell carcinoma, and pancreatic cancer; the risk of other cancers has not been evaluated so far. Herein, we examined the possible association of E318K and a novel variant of the MITF gene, V320I, with the risk of cancers of different sites of origin in a Polish(More)
The population frequencies of the CDKN2A common variants remain undetermined. In Poland, there is a common variant of the CDKN2A: an alanine to threonine substitution (A148T), which has been detected in other populations. We have recently showed that it is significantly overrepresented among Polish melanoma patients when compared to general population.(More)
We identified 4316 unselected incident cases of early-onset breast cancers (<51 ears of age at diagnosis) in 18 Polish hospitals between 1996 and 2003. We were able to obtain a blood sample for DNA analysis from 3472 of these (80.4%). All cases were tested for the presence of three founder mutations in BRCA1. The proportion of cases with a BRCA1 mutation(More)
Both hereditary and environmental factors are important in the aetiology of malignant melanoma. Among the risk factors for malignant melanoma are immunodeficiency and immunosuppression. The recently identified NOD2 gene is involved in the regulation of immune function through activation of the transcription factor nuclear factor-kappaB (NF-kappaB). Three(More)
