Study Population
Description
- INCLUSION CRITERIA:
Enrollment in this study will be limited to individuals with non-syndromic unilateral or bilateral cleft lip with or without cleft palate and their unaffected relatives, from families which meet the following criteria:
- A cluster of 2 or more affected first degree relatives, such as a parent and two offspring or 2 siblings, or
- The occurrence of oral clefts in each of 2 generations in either the proband's paternal or maternal lineages.
- The occurrence of oral clefts in 2 or more cousins (up to second cousins)
The subject population is comprised of probands and their families previously examined at the IBN-AL NAFEES Hospital or at other hospitals and clinics in the Syrian Arab Republic as well
as healthy controls from the same population. Consent documents are in Arabic language for non-English-speaking subjects
EXCLUSION CRITERIA:
Individuals unable to provide consent, except for cases who are children and mentally impaired persons with consenting parents or guardians.
