Introduction to Pierre Robin Sequence
Pierre Robin Sequence is a rare birth defect characterized by an underdeveloped jaw, backward displacement of the tongue, and upper airway obstruction.
Pierre Robin Sequence (PRS) is characterized by micrognathia, glossoptosis, and upper airway obstruction, resulting in breathing and feeding difficulties. It is a congenital condition where infants often have a smaller-than-normal lower jaw and a tongue that falls back into the throat, causing potential airway compromise.
Clinical Presentation of Pierre Robin Sequence
Pierre Robin Sequence manifests with micrognathia, glossoptosis, and upper airway obstruction causing breathing difficulties.
Definition and Characteristics
Pierre Robin Sequence is a rare congenital condition characterized by micrognathia, glossoptosis, and upper airway obstruction, leading to breathing and feeding difficulties in newborns.
Variability in Respiratory and Feeding Issues
Infants with Pierre Robin Sequence can exhibit a range of respiratory and feeding problems that vary from mild to severe, necessitating individualized care and management plans.
Causes of Pierre Robin Sequence
The exact causes of Pierre Robin Sequence are not fully understood, but genetic factors play a significant role, with changes near the SOX9 gene being a common genetic cause.
Genetic Factors
The etiology of Pierre Robin Sequence involves genetic factors, with changes near the SOX9 gene being a common genetic cause identified in affected individuals. This gene alteration contributes to the development of the condition present at birth.
DNA Changes near SOX9 Gene
DNA changes near the SOX9 gene are identified as a common genetic cause of isolated cases of Pierre Robin Sequence, contributing to the characteristic features such as micrognathia and tongue displacement seen in affected individuals.
