Question special

When a patient consents to having a genetic analysis performed, the genetic information gleaned is not only relevant to the patient, but also to the patient's family members since we share a proportion of our genetics (up to 100% in the case of identical twins) with our relatives. Are relatives of patients recieving genetic information protected under GINA? Are patients seeking genetic testing usually aware of this risk to their family members, and do they typically consult family members before seeking genetic testing?
