Prevalence of two BRCA1 mutations, 5382insC and 300T > G, in ovarian cancer patients from Ukraine.

Ovarian cancer is the seventh most common cancer in women worldwide and the leading cause of gynecological malignant diseases-related deaths in women. The most significant risk factor for ovarian cancer is an inherited genetic mutation in one of two genes: breast cancer gene 1 (BRCA1) or breast cancer gene 2 (BRCA2). The germline mutation c.

A HIGH FREQUENCY OF HERITABLE CHANGES IN NATURAL POPULATIONS OF DROSOPHILA MELANOGASTER IN UKRAINE.

Spontaneous mutations are thought to have a stable rate for a given species. If non-adaptive, they appear at low frequencies and are governed by drift. However, environmental factors have been reported to cause spread of non-adaptive mutations in populations, governed by mechanisms, such as genetic assimilation.

TP53 codon 72 polymorphic variants (Rs1042522) frequency in the Ukrainian population.

Objective: To estimate frequencies of polymorphic variants of TP53 codon 72 in the Ukrainian population.

Materials And Methods: We determined the allele frequencies for 148 healthy people. Genotyping was performed by allele specific polymerase chain reaction.

The frequency of BRCA1 founder mutation c.5266dupC (5382insC) in breast cancer patients from Ukraine.

Germ-line mutations in several genes, such as BRCA1 and BRCA2, are known to increase the risk of breast cancer. These heritable mutations are unequally represented among populations with different ethnic background due to founder effects and thereby contribute to differences in breast cancer rates in different populations. The BRCA1 mutation c.
