Addressing consumer grievances in medicine: policies and practices of newborn screening programs in the United States.

Newborn screening programs collectively administer the largest genetic testing initiative in the United States. The redress of grievances is an important mechanism for consumers to provide input into clinical and public health programs. In this study, we evaluated mechanisms for addressing consumer grievances in newborn screening programs.

BRCAPRO validation, sensitivity of genetic testing of BRCA1/BRCA2, and prevalence of other breast cancer susceptibility genes.

Purpose: To compare genetic test results for deleterious mutations of BRCA1 and BRCA2 with estimated probabilities of carrying such mutations; to assess sensitivity of genetic testing; and to assess the relevance of other susceptibility genes in familial breast and ovarian cancer.

Patients And Methods: Data analyzed were from six high-risk genetic counseling clinics and concern individuals from families for which at least one member was tested for mutations at BRCA1 and BRCA2. Predictions of genetic predisposition to breast and ovarian cancer for 301 individuals were made using BRCAPRO, a statistical model and software using Mendelian genetics and Bayesian updating.
