Fred A. Litwin Family Centre in Genetic Medicine

The Fred A. Litwin Family Centre in Genetic Medicine provides genetic assessments and genetic counselling for people who may be at risk of hereditary conditions based on their medical or family history. Your doctor may recommend that you come for a genetics appointment if:

  • You have been diagnosed with a genetic condition
  • You are concerned that you might have a genetic condition
  • Several of your family members have the same medical problem, and you are concerned about what it might mean for you or your children
  • You have questions about family planning because of a genetic condition in your or your partner's family
  • You have questions about genetic testing

About Genetic Conditions

Many genetic conditions are very rare. The following are some of the broad categories of conditions for which we offer assessments and counselling:

  • Connective tissue disorders (Marfan syndrome, Ehlers-Danlos syndrome, Loeys-Dietz syndrome)
  • Hereditary heart diseases (hypertrophic cardiomyopathy, long QT syndrome, arrhythmogenic right ventricular cardiomyopathy)
  • Hereditary kidney diseases (polycystic kidney disease)
  • Ocular diseases (retinitis pigmentosa, Stargardt’s disease)
  • Inherited metabolic diseases (Fabry disease, glycogen storage diseases, mucopolysaccharidoses)
  • Inherited neurological disorders (spinocerebellar ataxia, hereditary spastic paraparesis, Charcot-Marie-Tooth disease)
  • Hereditary cancer predisposition syndromes (Li-Fraumeni syndrome, paraganglioma/pheochromocytoma, Cowden syndrome) Note: We do not offer assessments and counselling for hereditary breast/ovarian or colon cancer. For assessments and counselling for hereditary breast or ovarian cancer, contact the Familial Breast & Ovarian Cancer Clinic. For assessments and counselling for colon cancer, contact the Zane Cohen Centre.


  • Comprehensive medical assessments for people who may have a genetic condition
  • Genetic counselling regarding the chances of inheriting a known genetic condition in the family, or the chances of passing on a genetic condition to children
  • Genetic testing, when recommended
  • Ongoing medical management for people diagnosed with inherited metabolic diseases (such as Fabry disease, urea cycle defects, glycogen storage diseases or other lysosomal storage diseases)
