Mutational analyses of RB and BRCA2 as candidate tumour suppressor genes in parathyroid carcinoma

Abstract excerpt

OBJECTIVE: Strong evidence indicates that at least one key tumour suppressor gene important for the development of malignant parathyroid tumours is located on chromosome 13, but the critical target gene remains unknown. Importantly, the region of acquired DNA loss includes two established tumour suppressor genes, the retinoblastoma gene, RB (RB1) and BRCA2. Resolution of whether RB or BRCA2 is the critical 13q...
