WitrynaBRCA genes are inherited in an autosomal dominant manner. This means that a person who has a mutation in either of the BRCA1 or BRCA2 genes has a 50% chance of passing on that mutation to each of their children. Men as well as women can be BRCA positive so a mutation can be passed from father to child as well as mother to child.

Microsatellite markers intragenic or in close proximity to both genes were used to analyze imbalances between the mutant and wild-type alleles.

WitrynaThe BRCA gene displays an autosomal dominant inheritance pattern, which means that the presence of only one mutant copy of the gene is sufficient to induce the characteristic. To put it another way, an individual only has to inherit a single copy of the gene in order to display the characteristic. 2.
