The Division of Genetics academic providers engage in clinical research and provide health care services at the Norton Children's Medical Group - Genetics Center located in the Novak Center for Children's Health in Louisville, Kentucky.  Services provided are center-based and outreach diagnostic evaluation and treatments for infants, children, and adults with, or at risk for, genetic disorders. 

The University of Louisville and Norton Children’s Genetics providers maintain national, state, and local prominence through their many unique clinical and diagnostic programs, research contributions, presentations, and teaching opportunities.

At the Genetics Center children are evaluated by clinical geneticists for a variety of reasons, including the presence of birth defects, developmental delay, intellectual disabilities, autism spectrum disorders, failure to thrive, or a suspected genetic condition.   All babies born in Kentucky receive genetic testing after birth screening for 55+ conditions. If a child tests positive for a condition or the results are unclear, follow-up testing will be ordered.

The University of Louisville and Norton Children’s Genetics team coordinates follow-up testing and any needed specialist appointments for newborns with abnormal or inconclusive screening results.

The clinical genetics team also provide long-term follow-up for children with known or suspected genetic conditions.  For example, comprehensive care of children with inborn errors of metabolism is provided through medical and dietary management and enzyme infusions.

Medical genetics evaluations are also provided to adults with concerns regarding various genetic conditions, including connective tissue disorders, neurological conditions, metabolic diseases, and lysosomal storage disorders.

Diagnostic Evaluation and Treatment of Genetic Disorders

The Norton Children’s Medical Group – Genetics Center provides care for children and adults with a wide range of genetic conditions.  Patients are evaluated by clinical geneticists and genetic nurse practitioner.

Personalized treatment plans are developed for each child’s or adult’s diagnosis and needs.  The multidisciplinary genetics team consists of medical geneticists, nurse practitioner, genetic counselors, metabolic nutritionists, social worker, and coordinator for the newborn screening program.


Genetic Testing

The Norton Children’s Medical Group – Genetics Center provides a large variety of genetic testing, depending on a diagnosis or suspected condition such as chromosome analysis or chromosome microarray analysis, various metabolic studies, whole exome/genome sequencing and imaging studies for children with multiple congenital anomalies, developmental delay, neurodiversity, autism spectrum disorder, or when the etiology is uncertain.


Genetic Counseling

Genetic counseling assists individuals and families in understanding information about birth defects or genetic disorders. This includes educating patients and their care team about patterns of inheritance, recurrence risks, natural history of diseases, genetic testing and planning options. Patients are connected with appropriate resources, such as support groups or specific types of medical clinics, locally and nationally.
