La ya doctora en biología Elena Beristain, ha defendido la tesis que relaciona la mutacion de dos genes, el BCRA1 y BCRA2, con la aparición del cancer de mama. Llegando a la conclusión de que entre el 5% y el 10% de los casos en que se presenta el cancer de mama, son consecuencia de la mutación de estos genes, que se heredan tanto por via paterna como materna.

PhD thesis on two genes involved in hereditary breast and ovary cancer cases treated in the Basque Country
Between 5 % and 10 % of breast cancer cases are hereditary, arising because the patient inherits from the father or mother a mutation in a gene that is susceptible to causing the illness. BRCA1 and BRCA2 have already been identified as two of the genes to be monitored. It is estimated that 30 % of hereditary breast cancer cases are due to mutations in one of these two genes (which suggests, at the same time, that there are other genes involved, but exactly how is still unknown). In any case, few of the mutations found in BRCA1 and BRCA2 could be clearly identified as pathological. The fact is that the mutations found were numerous; their variation even depending on the population. (sigue)
