Our Program

The Medical Genetics Program of Southwestern Ontario provides the following services for children and their families:

What to Expect

Infants and children come to the Medical Genetics department for many reasons. What to expect during your first visit depends on why you are coming to visit us. For more details, review our list of services, as shown above, and select the service you want.

General Genetics Clinic

The General Genetics Clinic provides assessment and genetic counselling for families with infants and children who have:

  • Birth defects and/or developmental delay
  • Family history of a known or potential genetic disease
    Geneticists are also available for in-hospital consultations at London Health Sciences Centre and St. Joseph’s Health Care, London.

When making an outpatient referral, the following information must be faxed to the clinic:

  • Reason for referral
  • Relevant documentation including consultations, notes and assessments
  • Results of any investigations performed to date

You will be sent a family history form to complete. When the clinic receives the family history form, an appointment can be scheduled.
Self-referrals are accepted, but they will be closely evaluated for appropriateness.

Inherited Metabolic Disorders

Inherited Metabolic Disorders are biochemical conditions that are genetic and can cause a person to become very ill. Though some Inherited Metabolic Disorders can be fatal, if interventions and treatments are started early, the severity of the condition usually lessens. Often, early treatment can prevent the condition from developing.
Our knowledge of Inherited Metabolic Disorders continues to grow, with our program expanding to meet the needs of our community and surrounding areas. Our specialized team offers excellent care to all our patients and their families.

Newborn Screening

Newborn screening is available to every newborn in Ontario. Newborn screening is a specialized way of identifying newborns at risk of disorders that can lead to significant health concerns. Newborns are screened for metabolic, endocrine and hematological conditions.
If your newborn does have a positive test result, a genetic counsellor will initiate a call to you or your family physician to arrange for confirmatory testing and discuss the implications of the results.

Currently, close to 30 conditions are screened for. All samples are initially processed within the Ontario Newborn Screening Program at the Children’s Hospital of Eastern Ontario (CHEO) in Ottawa.

Provincial IODE Genetics Resource Centre

The Provincial IODE Genetics Resource Centre was established in London, Ontario in 1993. The goal of the resource centre is to promote informed choice by increasing awareness of the role of genetics and how it affects all areas of health and well being.
The centre was established to:

  • Co-ordinate and facilitate genetic education
  • Provide Ontario families and professionals with current information and available resources about genetic conditions

A genetic support group directory was created, as well as information on approximately 200 genetic conditions.
Hundreds of information requests are made every year from parents, patients, students and medical personnel. These requests come from all over the province, country and around the world.

Resource Centre Library

The Resource Centre provides a research area for professionals and the community. The library houses the most up-to-date literature on genetics and medical texts.
The Resource Centre and Library is open Monday to Friday, 8:30 a.m. - 4:30 p.m. To visit the Resource Centre, please call 519-685-8453 to arrange an appointment.
