Down Syndrome: Understanding

Down Syndrome: Overview

Down Syndrome (DS) is a genetic disorder caused by the presence of an extra copy of chromosome 21, a condition known as trisomy 21. This extra genetic material affects development, resulting in characteristic physical features such as a flat facial profile, upward slanting eyes, and a single deep crease across the palm. Individuals with Down Syndrome often experience developmental delays and intellectual disabilities, though the severity can vary widely. Health complications associated with Down Syndrome can include congenital heart defects, respiratory issues, and a higher susceptibility to infections. Signs and symptoms of Down Syndrome include distinct facial features like a flat facial profile, upward slanting eyes, and a single deep crease across the palm. Developmental delays and intellectual disabilities are common, though their severity varies. Other health issues can include congenital heart defects, respiratory problems, and a higher risk of infections.

The pathophysiology of Down Syndrome centers on the presence of an extra copy of chromosome 21, known as trisomy 21, which disrupts normal genetic and biochemical processes. This genetic anomaly leads to overexpression of genes on chromosome 21, affecting various systems in the body. The overexpression contributes to developmental delays and intellectual disabilities by altering brain structure and function, particularly affecting neuronal connectivity and synaptic plasticity. Additionally, it impacts the cardiovascular, immune, and endocrine systems, leading to common health issues such as congenital heart defects, immune system deficiencies, and thyroid dysfunctions. The complex interplay of these genetic and biochemical changes underlies the diverse clinical manifestations of Down Syndrome.

Down Syndrome is typically diagnosed through a combination of prenatal screening and diagnostic tests. Screening tests, such as the first-trimester combined test and non-invasive prenatal testing (NIPT), assess the likelihood of the condition by analyzing maternal blood and ultrasound markers. If these screenings suggest a high risk, diagnostic tests like chorionic villus sampling (CVS) or amniocentesis are performed to confirm the diagnosis by directly examining the fetal chromosomes. After birth, Down Syndrome can be diagnosed based on physical characteristics and confirmed through a karyotype test, which analyzes the baby's chromosomes to identify the presence of an extra chromosome 21.

Treatment for Down Syndrome focuses on managing associated health conditions, providing supportive therapies, and promoting social inclusion and education. Medical interventions often address congenital heart defects, respiratory issues, and other health concerns through surgeries, medications, and therapies tailored to individual needs. Early intervention programs encompass speech, occupational, and physical therapies to support development and independence. Educational strategies, including specialized schooling and individualized learning plans, aim to maximize cognitive abilities. Social support networks and community programs play a crucial role in enhancing quality of life for individuals with Down Syndrome, promoting their integration and participation in society.

Down Syndrome Emerging Drugs

ACI-24 : AC Immune SA

The anti-Abeta active immunotherapy candidate ACI-24 is designed to stimulate the immune system to produce antibodies that specifically target misfolded Abeta, prevent accumulation and enhance the clearance of amyloid plaques. The ACI-24 vaccine is liposome based and intended to treat neurological disorders caused by misfolded Aβ pathological protein. By incorporating the first 15 amino acids of human Aβ into a stacked β-sheet conformation on the liposome, ACI-24 induces the production of polyclonal anti-Aβ antibodies specific for soluble and insoluble aggregated forms of Aβ, including oligomers; Aβ oligomers are one of the toxic species that create pathogenesis in both persons with Alzheimer's Disease and in Down Syndrome. The drug is currently being evaluated in Phase I/II stage of development for the treatment of patients with Down Syndrome.
