Analysis of Downs syndrome with molecular techniques for future diagnoses

Area of Science:

• Genetics
• Human Genetics
• Genomic Medicine

Background:

• Down syndrome (DS) is a genetic disorder characterized by trisomy 21.
• Current identification relies on clinical symptoms and chromosomal analysis, lacking biochemical and molecular methods.
• Non-Mendelian inheritance patterns are observed in DS.

Purpose of the Study:

• To review advancements in genetic analysis for Down syndrome.
• To explore the potential of whole exome sequencing (WES) in identifying Down syndrome markers.
• To suggest WES as a diagnostic tool for DS.

Main Methods:

• Review of current literature on genetic disorder identification.
• Focus on high-throughput sequencing technologies.
• Discussion of whole exome sequencing (WES), next-generation sequencing (NGS), and whole genome sequencing (WGS).

Main Results:

• Whole exome sequencing (WES) has significantly advanced the identification of disease-causing genes.
• WES, NGS, and WGS are powerful tools for identifying disease markers.
• There is a need for molecular analyses in DS diagnosis.

Conclusions:

• Whole exome sequencing (WES) shows promise for identifying specific marker regions in Down syndrome.
• Implementing WES in children with DS could enhance diagnostic capabilities.
• Further research into molecular markers for DS is recommended.
