Genetics departments in hospitals provide support for individuals with genetic disorders or those who need to know more about a suspected genetic disorder. They also provide diagnostic evaluations, genetic counseling, and treatment for genetic conditions. While it is unclear whether most hospitals have a genetics department, some hospitals, such as St. Louis Children's Hospital, Nationwide Children's Hospital, and Children's Hospital of Philadelphia, have a dedicated division or department for genetics and genomic medicine. These hospitals offer a range of services, including genetic testing, counseling, and treatment for various genetic diseases.

What You'll Learn
Genetic counselling
During a genetic counselling session, the counsellor collects the individual's or family's personal and medical history. This information helps them determine the likelihood of a genetic condition being present. Based on this assessment, they can advise on whether genetic testing is appropriate. If testing is recommended, counsellors interpret the results, conveying the information in a way that addresses the concerns of the individual or family. They also provide psychological support to help them adapt to their condition or risk.

Genetic testing
The process of genetic testing typically begins with a consultation with a genetic counselling assistant, who will gather information about the patient's medical history and family pedigree. This initial consultation may be conducted over the phone, and it is important to note that sensitive information may be requested during this call. Following the consultation, the patient will undergo a genetic test, and subsequent appointments will be scheduled to discuss the results and any necessary treatments or further tests.
It is important to note that not all hospitals have dedicated genetics departments, and patients may need to seek specialised care at specific centres or clinics. These clinics offer diagnostic evaluations, genetic counselling, and treatments for individuals of all ages, from pre-conception to adulthood. Additionally, some companies, such as Invitae and Labcorp, offer advanced genetic testing that can be integrated into medical practices, providing meaningful insights to improve patient care.

Chronic genetic disorders in children
A genetic disorder is a health problem caused by one or more abnormalities in the genome. It can be caused by a mutation in a single gene or multiple genes or by a chromosomal abnormality. Genetic disorders include certain types of birth defects, chronic diseases, developmental problems, and sensory deficits that are inherited from one or both parents. Chronic genetic disorders are common in children's hospitals, with 96% of chronic childhood disorders being partly or wholly genetically determined. Children with single-gene and chromosomal disorders have hospital stays that are twice as long as those without any pre-existing chronic medical disorder.
There are over 6,000 known rare diseases, and 8 out of 10 of these have a genetic cause. Many rare diseases are chronic and life-threatening, and most currently have no effective treatment. On average, it takes over four years to receive an accurate diagnosis of a rare disease. Mitochondria, the energy-creating parts of our cells, can be affected by rare diseases.
Some examples of chronic genetic disorders in children include:
- Down syndrome (Trisomy 21): Children with Down syndrome have an extra copy of their 21st chromosome. About half of these children also have a congenital heart condition.
- Williams syndrome: This is caused by a missing piece of chromosome 7. Children with Williams syndrome have distinctive facial features and a very social personality. They also have a narrowing of the large blood vessel that carries blood from the heart to the rest of the body, which can cause heart and blood vessel problems.
- Alagille syndrome: This multisystem disorder usually impacts the heart, liver, and eyes. It is generally caused by a genetic change in one of two genes: Jagged1 or Notch 2.
- Hereditary hemorrhagic telangiectasia (HHT): HHT is a genetic disorder associated with abnormal connections of blood vessels, called arteriovenous malformations (AVMs). These can be present in the lungs, brain, liver, or gastrointestinal tract. People with HHT often have significant nosebleeds and can have red spots on their skin, lips, and tongue.
- Tuberous sclerosis complex (TSC): TSC involves abnormal growth in the skin, brain, heart, kidneys, eyes, and lungs. Patients with TSC will often have benign tumors that may require surgery for removal, but these often decrease in size or disappear as the child matures.
- Congenital heart disease (CHD): CHD is the most common birth defect in humans and can run in families.
Genetic counselling and testing are important tools for diagnosing and understanding genetic disorders. Newborn screening can be used to check for certain genetic disorders that can be diagnosed and treated early in life. Brain imaging can also be used to make diagnoses before reading even starts, as in the case of dyslexia. Treatment for genetic disorders varies depending on the specific disease. For example, symptoms of autism may be treated with medication, behavioural, and educational interventions, while physical symptoms of certain genetic diseases can be corrected with surgery.

Genetic research
Genetics departments in hospitals often collaborate with other departments, such as pediatrics, oncology, and research centres, to provide comprehensive patient care and contribute to genetic research. For example, the Division of Human Genetics at the Children's Hospital of Philadelphia has a Clinical Genetics section and collaborates with various departments within the hospital to ensure continuity of care and individualized treatment for children with genetic conditions. Similarly, St. Louis Children's Hospital's Genetics and Genomic Medicine department has three onsite genetics laboratories, enabling quicker diagnosis and treatment for patients with suspected or confirmed genetic disorders.
Hospitals that specialize in pediatric care often have a strong focus on genetic research and treatment. This is because genetic disorders are common among children admitted to hospitals, and these patients tend to have longer stays and higher medical expenses. For instance, Children's Hospital Colorado has a Clinical Genetics and Inherited Metabolic Diseases Program that provides diagnosis, genetic counselling, and treatment for children with known or suspected inherited diseases, birth defects, or developmental delays. University Hospitals, with locations in Cleveland and Buffalo, also have departments dedicated to genetic services, combining research and clinical expertise to better understand and treat genetic disorders.
In addition to patient care, hospitals also contribute to genetic research by conducting studies and collaborating with universities and research institutions. For example, the University Hospitals of Cleveland collaborated with Case Western Reserve University and the Roswell Park Cancer Institute on a study investigating the burden of genetic disease on inpatient care in a children's hospital. This study highlighted the high prevalence and impact of genetic disorders, particularly in pediatric patients.
Overall, while the presence of a dedicated genetics department may vary across hospitals, genetic research and clinical applications are integral aspects of modern healthcare. Hospitals play a crucial role in advancing our understanding of genetics, developing new treatments, and providing specialized care for patients with genetic disorders.

Medical genetics workforce
Genetics departments in hospitals focus on clinical genetics and laboratory genetics. Clinical genetics involves the diagnosis and treatment of genetic disorders, while laboratory genetics involves the analysis of genetic material and the development of new genetic technologies.
The University Hospitals Center for Human Genetics combines research and clinical expertise to better understand and treat genetic and metabolic disorders. They provide diagnostic evaluations, genetic counselling, and treatment for genetic conditions. Similarly, the Division of Genetic and Genomic Medicine at Nationwide Children's Hospital aims to improve the lives of individuals with genetic conditions by delivering compassionate, family-centred care. They offer genetic counselling, education, and advocacy and provide diagnostic evaluations and treatments for genetic diseases.
The genetic workforce is comprised of clinical geneticists and laboratory geneticists. As of 2019, there were 491 clinical geneticists in the US, most of whom were female (59%) and White (79%), worked in academic medical centres (73%), and engaged in telemedicine (33%). They reported an average of 13 new and 10 follow-up patient visits per week, with an average work week of 50 hours. Laboratory geneticists, on the other hand, mostly work in academic medical centres or commercial laboratories. The majority are PhDs, followed by physicians and other degree combinations.
There is a growing demand for genetic services, and a gap between the demand for genetic services and the capacity of the workforce. This highlights the need to increase the number of clinical geneticists and enhance interdisciplinary teamwork.
