Greenberg Center for Skeletal Dysplasia

The Kathryn and Alan C. Greenberg Center for Skeletal Dysplasias is part of the McKusick-Nathans Institute of Genetic Medicine at Johns Hopkins University in Baltimore, Maryland. Our mission is to provide the best coordinated healthcare to patients with a wide variety of bone conditions; to conduct research to determine the genes responsible for these conditions and the best therapies to treat them; and to spread the benefits of our research to the wider community through the training of faculty and building of nationwide registry of patients with bone conditions.

Why choose Johns Hopkins The Kathryn and Alan C. Greenberg Center for Skeletal Dysplasias?

Our History

The Alan and Kathryn Greenberg Center for Skeletal Dysplasias began in the late 1950’s as the Moore Clinic, under the leadership of Dr. Victor McKusick and his assistant, Kay Smith. The center began in order to support Dr. McKusick’s categorizatrion and care of short stature patients. Dr. McKusick began attending Little People of America (LPA) meetings in the early 1960’s and helped create the Medical Advisory Board of the LPA.

The Greenberg Center was renamed in 1990 after a generous contribution was made by Kathryn and Alan Greenberg, who wanted to help support short statured individuals and their families. Mr. and Mrs. Greenberg have made it possible for the Greenberg Center to not only help short statured patients medically, but to also to provide resources, as well as give yearly scholarships to students with dwarfism.

Since 1990, the Greenberg Center has given over $50,000 in college scholarships to individuals with short stature and their families. Research conducted through the Center has yielded dozens of papers in medical journals, presentations, and posters presented at medical national conferences. The Greenberg Center expanded to include the Combined Endocrine-Genetics Clinic in 2010, the multi-disciplinary Cleft Clinic in 2012, and the Craniofacial Clinic in 2014. New growth charts for achondroplasia have been created by Dr. Julie Hoover-Fong, Director of the Greenberg Center, including height, weight, and BMI standards.

Our Approach

Our clinic is dedicated to quality medical care in the diagnosis and treatment of those with aortic aneurysm syndromes and related disorders. Through expert team management, research and family education, we strive to continually increase the quality of life of our patients. Our approach to patient care includes:

Application of evidence-based medical therapy and research to the individualized treatment of our patients, including medication, lifestyle modifications and incorporation of genetic and familial factors
Quality aortic imaging through our cardiology and radiology departments
Multidisciplinary care coordination may be required with specialists in vascular, neurovascular and cardiothoracic surgery, as well as nonvascular specialties, such as ophthalmology, orthopedics and pulmonary.
Family assessment and screening, if appropriate
Education and support of patients and their families through emergency preparedness, connections for psychosocial support and other educational documentation
We look forward to addressing your concerns and providing you excellent care.

John McGready, PhD

Faculty Member

John McGready has been a faculty member in Biostatistics at the Johns Hopkins Bloomberg School since 1999. Since joining the faculty at Hopkins, he has split his time between statistical education, research collaborations , and his own research. As an educator, he has taught both introductory and intermediate biostatistics courses to graduate students in public health. He has enjoyed fruitful and interesting collaborations with researchers from the Schools of Medicine, Public Health and Nursing at Johns Hopkins.

Kerry Schulze, PhD

Faculty Member

Kerry Schulze earned her PhD at the Johns Hopkins Bloomberg School of Public Health in the Department of International Health Program in Human Nutrition assessing the relationship between calcium metabolism and bone mineralization in preadolescent and adolescent girls with cystic fibrosis. She has remained on the faculty in the Program in Human Nutrition, primarily running a research laboratory that assesses vitamin and mineral status of women and children from community-based studies in Nepal, Bangladesh, and elsewhere where the risk of vitamin and mineral deficiencies is high. This interest has translated more broadly into the assessment of nutritional status—whether micronutrients, anthropometry, body composition, or physical activity—of groups and populations at risk of poor nutritional status across the spectrum from malnutrition to chronic disease risk. Her work with the Greenberg Center has centered around characterizing growth and body composition, and related risk of chronic disease, among children and adults with skeletal dysplasias.
