Insights

This study reports the tenth sibling case of complete unilateral agenesis of the diaphragm. Families with a prior diagnosis face a higher recurrence risk, necessitating genetic counseling and antenatal screening for future pregnancies.

Area of Science:

  • Medical Genetics
  • Developmental Biology
  • Pediatric Surgery

Background:

  • Congenital diaphragmatic hernia (CDH) is a serious birth defect.
  • Complete unilateral agenesis of the diaphragm is a rare form of CDH.
  • Understanding recurrence risks is crucial for affected families.

Observation:

  • This report details the tenth instance of complete unilateral agenesis of the diaphragm occurring in siblings.
  • This specific congenital anomaly (McKusick 22240) presents a unique genetic challenge.

Findings:

  • A familial pattern suggests a significant recurrence risk for congenital diaphragmatic hernia in subsequent offspring from affected parents.
  • The tenth sibling occurrence highlights a potential genetic predisposition.

Implications:

  • Genetic counseling is strongly recommended for families with a history of complete unilateral agenesis of the diaphragm.
  • Antenatal ultrasound screening should be considered for subsequent pregnancies to detect potential recurrence early.
  • Early detection and management are vital for improving outcomes in congenital diaphragmatic hernia.

Sex-linked Disorders01:43

Sex-linked Disorders

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

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...
Atelectasis II: Pathophysiology01:10

Atelectasis II: Pathophysiology

Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
Esophageal Achalasia01:27

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
Hiatal Hernia01:25

Hiatal Hernia

A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...
