Brad T. Tinkle, M.D., Ph.D., is the Medical Director of Clinical Genetics at Advocate Children’s Hospital in Chicagoland. His clinics include Ehlers-Danlos (for adults, children, and families) and pediatric Down’s Syndrome. (For appointment scheduling information, go to www.leftpawpress.com and download the complimentary DIY bookmark).
Prior to his current position, Dr. Tinkle was a clinical and clinical molecular geneticist at Cincinnati Children’s Hospital Medical Center (CCHMC). He specializes in caring for individuals with heritable connective tissue disorders such as Ehlers-Danlos syndromes, Marfan syndrome, osteogenesis imperfecta, and achondroplasia among the many. He served as director of the Skeletal Dysplasia Center (CCHMC), co-director of the Marfan/Ehlers-Danlos syndrome clinic, as well as director of the Connective Tissue Clinic.
In addition, he serves as associate director in the Clinical Molecular Genetics Laboratory at CCHMC. He earned a bachelor’s in science for engineering (BSE) in genetic engineering from Purdue University in 1989. He received his Ph.D. in Human Genetics from the George Washington University in the District of Columbia in 1995.
He attended medical school at Indiana University and completed a pediatric/clinical genetics residency at CCHMC. He also finished a fellowship in clinical molecular genetics at CCHMC following residency.
He formerly served on the Board of Directors and on the Professional Advisory Network of the Ehlers-Danlos National Foundation.

The diagnosis of a fetal skeletal dysplasia is more often incorrect. The Skeletal Dysplasia Center in collaboration with the Fetal Care Center is using the most advance imaging techniques (fetal MRI) in conjunction with ultrasound imaging and growth characteristics to better delineate such dysplasias in utero as evident in our patient in this case report.

Diagnosis of a disorder based on subjective (exam only) clinical grounds is often poorly reproduced but made worse when the diagnostic criteria are different due to age, gender, athletic training, etc. Spearheading this international collaborative effort, experts in the field of connective tissue disorders agree to apply more simplistic criteria to better manage patients rather than focus on diagnostic labels.

Although a known life-threatening complication of achondroplasia, the AAP guidelines in the timing, mode of imaging, and interpretation of the test results are poorly delineated. A series of patients were evaluated under a clinical protocol and the sleep study results were carefully analyzed to reveal a unique pattern that will likely help in the determination of the severity of central sleep apnea in this patient population.

Hemimegalencepahly is a life-threatening disorder often accompanied by untractable seizures. Through careful review, it became apparent that the natural history of this condition relates to the underlying cause (idiopathic v. syndromic). This observation aided in the prognosis of this disorder thereby affecting management including hemispherectomy.

Multiple fractures particularly in young children are concerning for trauma, and where unexplained, for abuse. A multitude of genetic conditions can cause bone fragility but helpful clinical and/or biochemical delineation in the context of multiple fractures has not been described previously.
