We take on ourselves to search for the families, explain to them what are the purposes of the research and their consequences. If we suspect a new gene, we will ask the parents or patients to sign informed consent forms according to our approved Helsinki board. We will take a sample of 10 cc blood in order to extract DNA. The DNA will be extracted in the genetic lab in Israel. A coded DNA will be sent to the researcher abroad. After 12 years the sample will be returned coded to the lab in Israel.
