Summary
Orofacial clefts (OFCs) are common birth defects impacting head and neck development. This review covers OFC embryology, genetics, and epidemiology, highlighting recent genetic research.
Area of Science:
- Medical Genetics
- Developmental Biology
- Public Health
Background:
- Orofacial clefts (OFCs) are the second most common congenital birth defect in the U.S. and the most frequent head and neck malformation.
- OFCs encompass cleft lip with or without cleft palate (CL/P) and cleft palate only (CPO).
- These conditions impose significant psychological and socio-economic burdens, necessitating multidisciplinary care.
Purpose of the Study:
- To provide a comprehensive review of orofacial clefts.
- To detail the embryology, classification, epidemiology, and etiology of OFCs.
- To present recent advancements in the genetics of OFCs.
Main Methods:
- Literature review of embryology, classification, epidemiology, and etiology.
- Synthesis of current research on the genetic factors contributing to OFCs.
- Analysis of recent genetic findings in the context of OFC development.
Main Results:
- OFCs result from a complex interplay between genetic and environmental factors.
- Recent genetic studies are elucidating specific pathways and genes involved in OFC development.
- A detailed understanding of OFC etiology is crucial for effective management.
Conclusions:
- Orofacial clefts are multifactorial congenital anomalies with significant health implications.
- Advances in genetics offer new insights into OFC pathogenesis.
- Continued research is vital for improving prevention and treatment strategies for OFCs.

Sutures of the Skull
8.9K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Teeth
1.1K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Cystic Fibrosis: Pathogenesis
490
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Tooth Anatomy
1.4K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Cohesins
4.9K
Cohesin protein complexes are a molecular glue that holds two sister chromatids together. They play an important role both in mitosis and meiosis. In mitosis, all cohesin complexes present on the chromosomes are removed before the start of the anaphase stage.
Cohesin complexes in Meiotic Division
Meiosis involves two distinct rounds of chromosomal segregation and cell divisions— Meiosis I followed by Meiosis II – producing four daughter cells. Meiosis I includes the separation of...
