Our study supports this lower detection rate in the very youngest age group, in contrast to the overall trend to increasing frequency of BRCA1/2 at younger ages seen in population based testing.21 This is similar to the lower rates found in ovarian cancer <30 years.22 The Myriad study6 also showed a similarly increased detection rate for TNBC <30 years. The gene discussed is BRCA1; the disease is ovarian carcinoma.
