Is cleft lip a chromosomal disorder?
It includes cleft lip, cleft lip with palate (CLP), and cleft palate (CP). Chromosomal etiology accounts for 6% of all children with OFC [1]. In birth cohort studies on clefts the most widely reported chromosomal disorders are trisomies 18 and 13 with poor survival beyond the age of one year [2–4].

- Oculo-auriculo-vertebral spectrum (OAV) / Goldenhar syndrome / hemifacial microsomia.
- Van der Woude syndrome.
What is the most common birth defect?
The most common severe birth defects are heart defects, neural tube defects and Down syndrome. Although birth defects may be the result of one or more genetic, infectious, nutritional or environmental factors, it is often difficult to identify the exact causes. Some birth defects can be prevented.

What are the three most common syndromes associated with cleft lip?
Pierre Robin sequence. Stickler syndrome. Velocardiofacial syndrome (VCF) Treacher Collins syndrome.
What type of birth defect is cleft lip?
Can drinking while pregnant cause cleft lip?
“Prenatal exposure to alcohol, especially excessive amounts at one time, can adversely affect the fetus and may increase the risk of infant clefts.” The causes of clefts are largely unknown, but both genetic predisposition and environmental factors are believed to play a role in their development.
