Our genetics team is a trusted resource for patients of any age with genetic concerns. Our experts offer services for children and adults at Dayton Children’s or our off-site locations, as well as providing education to healthcare professionals, students and the community.

conditions we treat

Our genes help make us unique. Inherited from our parents, they go far in determining our physical traits, like eye color and the color and texture of our hair. They also determine things like the amount of oxygen blood can carry, and the likelihood of getting certain diseases.

Our genetics specialists see patients of all ages, children and adults, at any time in the lifecycle and with any of the following conditions:

programs & clinics

metabolic clinic

Our board-certified biochemical geneticists work alongside our nurses and metabolic dietitians to diagnose, treat, and prevent metabolic disorders. We provide follow-up care for abnormal newborn screening results, ongoing management for children and adults with confirmed metabolic conditions, and nutrition planning tailored to each patient’s needs. For children requiring enzyme replacement therapy or other advanced treatments, our team coordinates care and provides long-term monitoring to support their health and quality of life.

fetal care medicine

Specialists at Dayton Children’s work closely with physicians throughout our community to provide the best possible care for babies during pregnancy and in the early stages of life.

When problems are detected during pregnancy, advanced diagnostic testing, genetic counseling and advanced treatment during pregnancy and after birth are available to you.. Many of our consults can be a virtual visit.

multidisciplinary care teams

Our genetics team collaborates with other specialists at the hospital to ensure that each child receives comprehensive, coordinated care, including the following programs and clinics.

community education presentations

Dayton Children’s is committed to helping improve the health status of all children in our community. Part of these efforts include supporting community partners through education and outreach. Many of our programs are now available on video and can be provided virtually through various video conference platforms.

Request an education presentation by filling out our form or contact our genetics health educator at 937-641-3800 for educational resources or to schedule a visit with our community outreach specialist. Our genetic counselors and physicians are available to present to nurses, PAs, physicians and other health care providers on any topic of interest in genetics.

presentations for schools & other community partners

Topics include genetic causes of birth defects and introduces common multifactorial birth defects due to complex inheritance. We will focus on the importance of making great choices for our health and how that could impact future generations. Healthy habits formed now lead to healthy offspring later and will help reduce Ohio’s infant mortality rate.

Only five drops of blood are needed to identify babies at risk for many serious medical conditions, many of which are genetic. Identifying and treating these conditions early in a baby’s life can prevent lifelong disabilities, and possible death. Learn more about the history of newborn screening and how it can save a baby’s life.

Importance of family health history: Genomics plays a role in many diseases. An individual’s genetic makeup may put them at higher risk than the general population, but their lifestyle and environment also play a role. Collecting family health history is the first step towards identifying risk. Learn more about how to collect and share this important information.

According to the CDC, sickle cell disease is one of the most common single gene disorders worldwide and affects more than 100,000 individuals in the United States. In this program, we will focus on various aspects of sickle cell disease including the underlying genetic causes, complications, and management of the disease. This program is provided through collaboration with the West Central Ohio Comprehensive Sickle Cell Center located in the Division of Hematology at Dayton Children’s. 

Fetal alcohol spectrum disorder (FASD) is a term used to describe a group of conditions that can occur in a person who was exposed to alcohol during pregnancy. The range of effects include physical, mental, behavioral and/or learning disabilities. In this program, we will focus on the effects of alcohol on a baby’s development during pregnancy and discuss how FASDs can be prevented for future generations.

This program introduces careers in medical genetics, including the role of the medical geneticist, genetic counselor, nurse, cytogenetic and molecular laboratories. Through a combination of clinical photos and real-life case examples, students will understand how genetic conditions are diagnosed, treated and/or managed.

before your visit

Before you arrive, we ask that you pre-register for your visit by calling 937-641-4000 option 3. The pre-registration process allows our team to collect your insurance information required to obtain prior authorizations. Delaying or skipping this step may cause a delay in care or billing issues.

during your visit

Please allow 1 to 1.5 hours to cover registration time, your appointment, and lab time (if needed).

During your first visit with one of our genetic specialists, they may ask questions about medical conditions that run in your family, including birth defects, developmental delays, autism, cancer, cardiovascular disease and more. Before your visit, reach out to family members to collect information about your family’s health history. While collecting this history, please respect your family’s privacy – some individuals may not be comfortable sharing.

health information to collect:  

  • Important diagnoses as a child and as an adult 
  • Name of condition(s) 
  • Age of diagnosis 
  • Any cancer history 
  • Cardiovascular disorders
  • Any health conditions present in multiple relatives across generations  
  • Age of onset

other information to collect: 

  • Age
  • If deceased, age and cause of death 
  • Ethnicity, race 
  • Lifestyle and environmental factors
  • Exposures that may have increased risk 

Family health history can be stored as a list. To help record this information, use the CDC’s My Family Health Portrait tool.

after your visit – insurance coverage and prior authorization

Insurance coverage for genetic testing will be discussed with you at your appointment. During your appointment, the genetics provider will go over your personal and family history and will determine what type of testing is needed. However, please note that there are specific guideline requirements for genetic testing and you may or may not require testing. Testing involves a simple blood test or a spit test. No fasting or special instructions are required.

Prior authorization may be needed for genetic testing and your genetics provider will discuss prior authorization during or after your visit. We are unable to perform prior authorization for genetic testing prior to your appointment since most insurance companies require a genetics visit before authorization can be completed.

MTHFR polymorphism genotyping

In the course of their healthcare journeys, some families may come across information about a gene called MTHFR. Sometimes families first learn about this by:

  • doing a genetic test to help with medication management 
  • a doctor ordering testing for certain variations in this gene when there have been blood clots or the loss of a pregnancy
  • doing research online

What is MTHFR polymorphism genotyping?

There are two particular changes in this gene – called C677T and A1298C – which are very common among the general population. In fact, more than 40% of Caucasian people will have one or two copies of the C677T variant! These variations are so common, we don’t think of them as a “mutation” in the genetics community. Instead, we call them “polymorphisms”. A polymorphism is a genetic variation that is so common it can be considered a typical human variation.

Because this change is so common, in the past it has been linked to multiple health problems, including blood clots, heart issues, pregnancy loss, psychiatric disease, vision issues, and more! As time has gone by, we’ve learned that these health issues aren’t directly tied to these changes in the MTHFR gene, but just happened to show up in studies because so many participants have these polymorphisms.

misinformation about MTHFR

Unfortunately, a lot of online information about these variations can sometimes be misleading. Many families want answers to their health concerns. In the process of trying to figure out what’s going on, they might come across social media or websites that are being guided by older, outdated research. There are even some that try to profit from people who have these variations! Because of this, it’s very important to be careful about what information families rely on regarding MTHFR.

what you should know about MTHFR

The American College of Medical Genetics has an official position on testing for these polymorphisms can be found here. In general, genetics healthcare providers will advise against testing for these particular polymorphisms outside of specific circumstances
