Abstract
|
|
|
We analyzed germline mutations of the BRCAL gene in 29 Korean breast cancer patients, which included ①10 breast cancer patients with family history of breast or ovarian cancer, ② 7 early onset breast cancer patients without family history of
breast or
ovarian cancer(less than 40 years old at diagnosis) and ③12 breast cancer patients witout family history of breast or ovarian cancer(more than 40 years old at diagnosis), and 1 hereditary ovarian cancer patients, One nonsense mutation at codon
1815
encoding a truncated protein was detected in a breast cancer patients with family history of ovarian cancer. One missense mutation at condon 1630 was detected in a group of breast cancer patients without family history(more than 40 years old at
diagnosis), but still not determined whether it was polymorphism or not. Three polymorphisms were detected, which included 2 cases of silent mutation and a case of missense mutation. In early onset breast cancer group and a familial ovarian
cancer
patient, there was no detected mutation. We confirmed a germline BRCAL gene mutation in one Korean patient of hereditary breast-ovarian cancer family.
