Insights

Children with cleft lip and/or palate (CLP) often have other congenital issues. This study found 21% of CLP patients had major malformations or minor anomalies, highlighting the need for specialist evaluation.

Area of Science:

  • Medical Genetics
  • Developmental Biology
  • Pediatric Surgery

Background:

  • Congenital malformations frequently accompany cleft lip and/or palate (CLP).
  • Incidence rates and underlying mechanisms of these associated anomalies are not well-established.
  • A comprehensive understanding is crucial for patient management and genetic counseling.

Purpose of the Study:

  • To determine the incidence of additional major malformations and minor anomalies in a CLP population.
  • To compare malformation rates in CLP patients with the general population.
  • To investigate the organ systems most affected by malformations in non-syndromic CLP cases.

Main Methods:

  • Retrospective review of 245 patients with cleft lip and/or palate from a defined geographic area.
  • Systematic recording of major malformations and minor anomalies.
  • Comparison of observed malformation incidences against literature-based data from the general population.

Main Results:

  • 21% of CLP patients presented with major malformations or minor anomalies.
  • Recognized syndromes were identified in one-fifth of affected CLP patients.
  • Major malformations in non-syndromic CLP patients were most frequent in the musculoskeletal, central nervous, urogenital, and cardiovascular systems.
  • Significantly increased malformation incidence in CLP patients compared to the general population was observed for the central nervous (13x), ocular (7x), and craniofacial (7x) systems.

Conclusions:

  • A substantial proportion of CLP patients exhibit associated congenital anomalies, necessitating thorough specialist assessment.
  • The elevated incidence of malformations in ectodermal and ecto-mesodermal derived organs underscores the developmental link between craniofacial structures and the central nervous system.
  • Early identification and management of these associated anomalies are critical for improving outcomes in children with CLP.

Neurulation01:30

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
Sutures of the Skull01:22

Sutures of the Skull

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...
Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Cystic Fibrosis: Pathogenesis

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, but...
