Your Question

Is genetic testing available for orofaciodigital syndrome 1 (OFD1)? Does Medicaid cover genetic testing?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What is orofaciodigital syndrome 1 (OFD1)?

Orofaciodigital syndrome 1 (OFD1), also called orofaciodigital syndrome type 1, is a condition that affects the development of the oral cavity (the mouth and teeth), facial features, and digits (fingers and toes). This condition also causes polycystic kidney disease. Orofaciodigital syndrome 1 is caused by a change (mutation) in a gene called OFD1 which appears to play an important role in the early development of many parts of the body including the brain, face, limbs, and kidneys.[1] The syndrome is inherited in an X-linked dominant pattern. The diagnosis of OFD1 is sometimes made at birth, but it may be suspected only after polycystic kidney disease is found in later childhood or adulthood. Treatment for OFD1 typically focuses on the symptoms an individual has and may include surgery for cleft lip or palate , other oral abnormalities, or syndactyly (webbing of the fingers or toes).[2] Researchers have identified at least 13 potential forms of orofaciodigital syndromes, which are classified by their patterns of signs and symptoms. OFD1 is the most common form of orofaciodigital syndrome and differs from the other types mainly by its association with polycystic kidney disease.[1]

What are the signs and symptoms of orofaciodigital syndrome 1 (OFD1)?

Oral features of OFD1 may include a split (lobed) tongue, benign tumors of the tongue, cleft palatehypodontia (missing teeth), or other dental abnormalities. Facial features may include hypertelorism (increased width between the eyes), a small nose, micrognathia (small jaw) and other features. The fingers and toes may be short (brachydactyly), webbed or joined together (syndactyly), abnormally curved (clinodactyly), or have other abnormalities. There may be brain abnormalities (such as cysts) and kidney problems (such as polycystic kidney disease). About half of individuals with OFD1 have some degree of learning disability, which is usually mild. Almost all individuals with OFD1 are female.[2]

Is genetic testing available for orofaciodigital syndrome 1 (OFD1)?

Genetic testing for orofaciodigital syndrome 1 is clinically available. OFD1  is the only gene currently known to be associated with this condition. Testing is often used to confirm or establish the diagnosis in an individual when OFD1 is suspected.  A change (mutation) in the OFD1 gene is detected in up to 85% of individuals who have OFD1.[2] 

You can find laboratories offering clinical genetic testing for OFD1 on a website called GeneTests. To see a listing of clinical testing laboratories click here. GeneTests does not currently list laboratories doing research testing for OFD1.

Does Medicaid cover genetic testing?

The Federal Government determines which benefits must be provided to Medicaid recipients, and each state can decide whether to cover additional benefits. With the exception of newborn screening, each state has the option to cover genetic tests and services as a Medicaid benefit. As a result, each state differs with regard to its Medicaid coverage for genetic tests and services. There has been limited data on how each state provides Medicaid coverage for genetic tests and services.[3]

Medicaid may cover the cost of certain genetic testing, provided that certain criteria are met. Each individual should speak with their personal healthcare provider and/or their health plan administrator to find out if a specific test is covered or how to obtain coverage.
