Overview of Pierre Robin Sequence

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.​

Diagnosis and Incidence of Pierre Robin Sequence

Diagnosis of Pierre Robin Sequence involves evaluating the clinical triad of symptoms and the reported incidence rates vary widely.​

Reported Incidence Rates

The reported incidence of Pierre Robin Sequence varies widely, with approximate occurrences ranging from 1 in 8500 to 14٫000 births٫ highlighting the rarity of this congenital condition.

Diagnostic Methods

Diagnosis of Pierre Robin Sequence typically involves assessing the clinical triad of symptoms, which includes micrognathia, glossoptosis, and airway obstruction.​ Various diagnostic methods may be utilized to confirm the condition and tailor appropriate management strategies for affected individuals.

Associated Syndromes and Conditions

Pierre Robin Sequence may be associated with various conditions including Stickler Syndrome and Velocardiofacial Syndrome.​

Stickler Syndrome

Stickler Syndrome is one of the associated conditions with Pierre Robin Sequence, characterized by connective tissue abnormalities that may affect various parts of the body, including the eyes, joints, and hearing.​

Velocardiofacial Syndrome

Velocardiofacial Syndrome, also known as 22q11.​2 deletion syndrome, is another condition associated with Pierre Robin Sequence, characterized by a range of symptoms including cleft palate, cardiac anomalies, and characteristic facial features.​
