Genetics nurses treat patients that have genetic disorders (such as Huntingtons disease and cystic fibrosis), as well as provide counseling, screening and risk identification. The Genetic Nursing Credentialing Commission (GNCC) offers two genetics nursing credentials: the Advanced Practice Nurse in Genetics (APNG) and the Genetics Clinical Nurse (GCN). There are several professional societies for genetics nursing, include the International Society of Nurses in Genetics (ISONG), the National Coalition for Health Professional Education in Genetics (NCHPEG) and the National Organization for Rare Disorders (NORD). The U.S. Bureau of Labor Statistics predicts excellent, overall job growth for registered nurses. The median registered nurse salary is $62,450.
