What is FaceBase?

A group of research teams around the country studying facial development and facial characteristics.

www.facebase.org

Previous Work

FaceBase1

• We studied genetic data and facial shape in

Tanzanian children

• We showed that 3D photos could distinguish altered facial development from normal

Diagnostic Methods can be Improved

• Not sufficiently objective

Syndrome descriptions sometimes unclear

• Measurement Error

Manual measures are not very accurate or precise

• Limited Technology

Some 2D and 3D photos

Imprecise landmarking

Our Goals

• Library of 3D Facial Scans

• Diagnostic Aid for Physicians and Scientists

• “ Quantitative Science ”

How Does it Work?

1. Dense Surface Modeling

2. Geometric Morphometrics

• Automated facial landmarking

• Combine these analytical tools

• Apply to Clinical

Practice!

What will I need to do?

• Sign up for an appointment

• Sign consent forms:

- I will go over the consent form with you

- HIPAA, Patient Bill of Rights

Medical Information Form

• Includes consent for “ data-sharing ” ;

De-identified photos and data to be deposited in NIH FaceBase “ Hub ” database.

May be shared to qualified researchers approved by NIH “ Data Access

Committee ” .

3D Photos: How to Participate

1. 4 Face views will be collected

2. Tie hair back

3. Sit still just like for a normal picture

4. About 10-20 minutes total

5. Each participant will be given an anonymous study number to preserve confidentiality

What will happen to my Photo and Data?

1. We will take your 3D photo

2. We will analyze the 3D image

3. We will place anatomic landmarks on the 3D image

4. We will analyze the 3D images of patients with a specific known syndrome to define features characteristic of each syndrome

5. We will develop methods to distinguish among different syndromes

Key Points

• FaseBase2 is a research study, and is part of a larger international project

• We aim to improve how we diagnose genetic syndromes that include atypical facial development

• We need participants to take 3D Photos

• Let me know if you are interested and sign up for an appointment!

Thank you!
