Background:
Some head and facial abnormalities are rare and present at birth. Others are more common, and
may not show up until puberty. These conditions have different causes and characteristics.
Researchers want to learn more about these conditions by comparing people with face, head,
and neck abnormalities to family members and to healthy volunteers without such conditions.
Objectives:
To learn more about abnormal development of the face, head, and neck. To determine their
genetic variants.
Eligibility:
People who have not had surgery for facial trauma:
People ages 2 and older with craniofacial abnormalities (may participate offsite)
Unaffected relatives ages 2 and older
Healthy volunteers ages 6 and older
Design:
Participants will be screened with medical history and physical exam focusing on head, face,
and neck
Participants may be followed for several years. Visits may require staying near the clinic
for a few days.
A visit is required for the following developmental stages, along with follow-up visits:
Age 2 6
Age 6 10
Age 11 17
Age 18 and older
Visits may include:
Medical history
Physical exam
Questionnaires
Oral exam
Blood and urine tests
Cheek swab: a cotton swab will be wiped across the inside of the cheek several times.
Cone beam CT scan (CBCT): x-rays create an image of the head, face, teeth, and neck.
Participants will
stand still or sit on a chair for about 20 minutes while the scanner rotates around the head.
Photos of the head and face
Offsite participants will provide:
Copies of medical and dental records
Leftover tissue samples from previous surgery
Blood sample or cheek swab

This is a natural history study that will examine craniofacial anomalies that affect the
normal development of the facial skeleton, including birth defects and dentofacial
developmental abnormalities that express themselves with the growth of the individual.
Craniofacial anomalies may be rare and present at birth, such as hemifacial microsomia (1 in
every 7500 live births), or common, such as dentofacial deformities including the Habsburg
Jaw or mandibular prognathism (1% of the US population) that becomes apparent as a child
enters puberty. These are striking disorders as they involve the face and surrounding
structures, which is a focal point of self-identity and are intimately tied to quality of
life and daily function. The primary objectives of this study are:
1. To characterize rare and common craniofacial anomalies using both extensive clinical
evaluations, 3D cone-beam computed tomography-based geometric morphometric and
cephalometric analyses, and surface morphology
2. To determine the genetic variants for rare and common craniofacial anomalies.
The secondary objective is to establish a curated craniofacial phenomic/genomic database. The
study population includes individuals ages greater than or equal to 2 years with any
craniofacial anomaly but will focus on two specific conditions that affect facial skeletal
development: hemifacial microsomia and mandibular prognathism in children and adults. Up to
1920 subjects and family members as well as 480 healthy volunteers will be recruited through
referrals from NIH or outside providers and institutions. This natural history protocol will
generate research data that will improve the understanding and etiology of craniofacial
dysmorphologies.

- INCLUSION CRITERIA:
For Subjects:
- Age greater than or equal to 2 with craniofacial anomalies/abnormalities. Affected
family member (defined as an individual with a demonstrable relationship (any family
relationship no matter how distant) with the above subject in the pedigree) who
expresses craniofacial anomalies will be classified as a subject.
- Able to provide consent or in the case, of minors, have a legally-authorized
representative to provide consent.
For Unaffected Family Members:
- These family members are defined as individuals with a demonstrable relationship (any
family relationship no matter how distant) with a proband subject by pedigree who do
not express craniofacial anomalies.
- Greater than or equal to 2 years old.
- Able to provide consent or in the case, of minors, have a legally-authorized
representative to provide consent.
For Healthy Volunteers:
- In good general health.
- Greater than or equal to 6 years old.
- Able to provide consent or in the case, of minors, have a legally-authorized
representative to provide consent.
- Absence of a craniofacial congenital anomaly or malocclusion.
- No family history of a craniofacial syndrome.
EXCLUSION CRITERIA:
For All Participants:
- A history of facial trauma requiring surgical treatment and facial reconstruction.
- Refusal for both genetic testing and CBCT imaging. Participants must agree to at least
one of the two (both are not required to participate).
For Healthy Volunteers:
-Female volunteers who are pregnant or nursing.
