The Clinical Genetics Program at Johns Hopkins All Children’s offers comprehensive evaluation and medical management of children and families with a genetic condition. Our services include an initial diagnostic evaluation and complete clinical exam, genetic testing as appropriate or necessary, genetic counseling and follow-up. Our team includes a Board Certified clinical geneticist and a Board Certified genetic counselor.
Children and Teens may be seen for any of the following issues:
- One or more birth defects including cleft lip, congenital heart problems or others
- Unusual physical features
- Delayed or accelerated growth
- Developmental delay
- Known family history of a genetic condition, especially in a close relative
- Seizure disorder
We work closely with other medical specialists at Johns Hopkins All Children’s Hospital and in the Gulf Coast area to assist with management and treatment of any medical problems that a child may experience as a consequence of their underlying genetic condition.
Visiting our Practice
Patients are seen by appointment only. A parent or legal guardian must accompany the patient during office visits. Occasionally, it is impossible for a parent to attend. If that happens, you must give written permission for medical treatment in your absence.
If this is your first appointment, our office will mail several medical history forms and other paperwork that must be completed and brought along with you on the day of your appointment. You can also download the new patient forms directly from the website. If you are unable to bring these completed forms, please ensure that you arrive at least 30 minutes prior to your scheduled appointment to have time to complete them in our office. For return appointments, please arrive at least 15 minutes before your appointment to complete the necessary paperwork.
As a courtesy, our office will call to confirm each appointment. If you must cancel this appointment, please call the office at (727) 767-8491 or (800) 456-4543 ext. 8491 at least 48 hours in advance of your appointment date. Patients arriving greater than 30 minutes late for their scheduled appointment time may not be seen that day.
