For Healthcare Professionals


The role of diagnostic and predictive genetic testing in healthcare is growing. A genetic testing referral helps physicians provide the best possible care for their patients and chart a course of action when appropriate.

The Greenwood Genetic Center is a non-profit organization that is advancing the field of medical genetics through research, education and patient care. GGC's main campus is located in Greenwood, South Carolina with satellite offices in Charleston, Columbia, Florence, and Greenville. Services include clinical genetic services, diagnostic laboratory testing, research, and educational programs that provide important resources for patients in need. See a list of all of our clinical locations.

When it’s Time for a Genetic Consultation

Healthcare professionals refer patients for clinical services at the Greenwood Genetic Center when a patient has symptoms or features that could be caused by a genetic disorder or has a family history or a predisposing condition that indicates risk for a hereditary condition. GGC clinicians are experienced in evaluating patients at all stages of life and for any genetic concern. Areas of concentration include:

  • General Genetics Clinics – Children or adults may benefit from genetic services when they present with autism, birth defects, developmental delay, intellectual disability, teratogenic exposure, or any features that may indicate an inherited condition or syndrome.
  • Metabolic Genetics Clinics – Children or adults with features suggestive of a metabolic or mitochondrial disorder are seen in our metabolic clinics. Clinical biochemical geneticists, genetic counselors, dietitians, and neuropsychologists assess, diagnose, treat, and follow patients with a variety of metabolic disorders. Infants diagnosed through newborn screening are followed through these clinics as well.
  • Cancer Clinics – Genetic counseling for patients with a strong personal and/or family history of cancer can help them explore their true risks, possible genetic testing options, and risk management. The most common referrals are for patients with breast, ovarian, colorectal and/or uterine cancers. However, any patients with a family history of any cancer types may also benefit from referral.
  • Prenatal Clinics — Couples planning a family and pregnant women are frequently referred to GGC for preconceptional or prenatal risk assessments. Advanced maternal age, family history concerns, abnormal ultrasound findings and positive maternal serum screening are among the reasons physicians seek genetic counseling for their patients. Prenatal services are available in Greenville.
  • DDSN Clinic - Clients served by the SC Department of Disabilities and Special Needs are evaluated by a genetics team to assist in making a diagnosis, determining recurrence risk, and coordinating a plan for medical care and treatment. Clients may be referred to any of the GGC offices by their DDSN caseworker or provider.

The process for referral is uncomplicated. FAX referral forms are available for each GGC clinic, except prenatal. The professional staff at GGC welcomes questions and can help direct primary physicians to the most convenient GGC location.

One Mother's Story

One Mother's Story

After a long three-year struggle trying to have children, our son, Charlie, was born on April 18, 2009. He was our miracle...perfect in every way! When Charlie was five days old, our pediatrician called to notify us that one of the numbers from the heel prick test was a bit high. We headed to the hospital that afternoon for more tests. I will never forget the following day. It was cool and crisp - not a cloud in the sky....
