Common autosomal chromosomal abnormalities include Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), Patau syndrome (trisomy 13), and Turner syndrome (monosomy X). These abnormalities result from errors in chromosome number, leading to characteristic physical and developmental features. Diagnosis is often made through genetic testing such as karyotyping or chromosomal microarray analysis.

What are the possible causes of Down's syndrome?

When a baby is conceived, it receives genetic information from its parents in the form of 46 chromosomes: 23 from the mother and 23 from the father. In most cases with Down syndrome, the child receives an extra copy of Chromosome 21 - for a total of 47 chromosomes instead of 46.It's this extra genetic material that causes the physical features and developmental delays associated with Down Syndrome. This form of Down syndrome is called Trisomy 21.Down syndrome is caused by nondisjunction of this chromosome in a parent who is chromosomally normal.It is one of the most common chromosomal abnormalities in live-born children. The extra chromosome causes problems with the way the body and brain develop.Down syndrome or trisomy 21 is caused by nondisjunction of chromosome 21 in a parent who is chromosomally normal and is one of the most common chromosomal abnormalities in liveborn children.Down's syndrome is caused when there is an extra chromatin present in chromosome 21 when an child is born.

Down syndrome is caused by a genetic abnormality in Chromosome 21. It is highly unlikely that X-Ray exposure causes genetic abnormalities such as this. However, X-Rays are not recommended while pregnant.
