Overview of Shokeir Syndrome
The Pena-Shokeir syndrome is an autosomal recessive disorder characterized by arthrogryposis, facial anomalies, and potential lethality.
Definition and Characteristics
Pena-Shokeir Syndrome, also known as PSS, is an autosomal recessive disorder characterized by neurogenic arthrogryposis, facial anomalies, pulmonary hypoplasia, and fetal akinesia. It was first described in 1974 by Pena and Shokeir and is known for its potentially lethal nature.
Types of Shokeir Syndrome
Pena-Shokeir Syndrome Type I and Type II manifest as distinct forms of this autosomal recessive disorder, each with specific clinical features and outcomes.
Pena-Shokeir Syndrome Type I
Pena-Shokeir Syndrome Type I, also known as Pena-Shokeir Phenotype (PSP), is an autosomal recessive disorder marked by neurogenic arthrogryposis, facial anomalies, and pulmonary hypoplasia. It was first reported by Pena and Shokeir, with an estimated incidence of one in 12٫000 births.
Pena-Shokeir Syndrome Type II
Pena-Shokeir Syndrome Type II, also known as COFS Syndrome, is a rare, autosomal recessive degenerative disorder involving the brain, eyes, and spinal cord. Patients may exhibit varying survival rates depending on the severity of the condition.
Epidemiology of Shokeir Syndrome
The estimated prevalence of Pena-Shokeir Syndrome is around 1 in 12٫000 births٫ with specific associations with other syndromes as well.
Prevalence

Genetic Aspects of Shokeir Syndrome
Shokeir syndrome is an autosomal recessive disorder with complex genetic underpinnings, involving mutations in specific complementation genes.
Autosomal Recessive Inheritance
Shokeir syndrome follows an autosomal recessive pattern of inheritance, characterized by the involvement of specific complementation genes and a complex genetic etiology.
Clinical Features of Shokeir Syndrome
Shokeir Syndrome presents with manifestations such as neurogenic arthrogryposis, facial anomalies, pulmonary hypoplasia, and fetal akinesia deformation sequence.
Arthrogryposis
Arthrogryposis is a prominent clinical feature of Shokeir Syndrome, characterized by joint contractures and limited movements in affected individuals, contributing to the complex phenotypic presentation of the condition.
Facial Anomalies
Shokeir Syndrome includes facial anomalies such as micrognathia and camptodactyly, contributing to its distinctive phenotypic features alongside other clinical manifestations.
Diagnosis and Prenatal Screening
Prenatal diagnosis of Shokeir syndrome involves ultrasonographic and antenatal magnetic resonance imaging to detect features like arthrogryposis and facial anomalies.
Ultrasonographic Findings
Ultrasonographic findings in Shokeir Syndrome typically reveal features such as arthrogryposis, facial anomalies, and polyhydramnios, aiding in the antenatal diagnosis and management of affected individuals.
Antenatal Magnetic Resonance Imaging
Antenatal Magnetic Resonance Imaging plays a crucial role in detecting the features of Shokeir Syndrome, particularly aiding in the visualization of CNS abnormalities and associated anomalies alongside ultrasonographic findings for a comprehensive antenatal assessment.
Management and Treatment Approaches
Effective management of Shokeir Syndrome involves a multidisciplinary care team comprising specialists in genetics, pediatrics, orthopedics, and physical therapy to address the diverse needs of individuals affected by the condition.
Multidisciplinary Care Team
The effective management of Shokeir Syndrome involves the coordinated efforts of a multidisciplinary care team comprising genetic specialists, pediatricians, orthopedic surgeons, physical therapists, and other experts to provide comprehensive care tailored to the specific needs of each individual affected by the condition.
Prognosis and Complications
Shokeir Syndrome carries the potential for lethality due to its complex clinical manifestations and associated complications, necessitating comprehensive management strategies and care.
Potential Lethality
Shokeir Syndrome has the potential for lethality primarily due to its severe clinical manifestations and associated complications, necessitating vigilant management and care strategies to improve outcomes for affected individuals.
Research and Diagnostic Pathways
Molecular investigation studies and prenatal diagnostic studies play crucial roles in understanding and diagnosing Shokeir Syndrome for better clinical management and patient outcomes.
Molecular Investigation Studies
Molecular investigation studies play a significant role in unraveling the genetic complexities of Shokeir Syndrome, aiding in precise diagnosis, understanding the underlying molecular mechanisms, and paving the way for potential therapeutic interventions and genetic counseling strategies.
Prenatal Diagnosis Studies
