What causes fragmented chromosome?

Some of the possible causes of a chromosomal anomaly include: Maternal age — older women are at higher risk of having children with an abnormality. Meiosis mistake — an error in the mother or father’s reproductive organs that causes an egg or sperm to have less than 23 pairs.

What happens if chromosomes are damaged?

Chromosomal abnormalities can have many different effects, depending on the specific abnormality. For example, an extra copy of chromosome 21 causes Down syndrome (trisomy 21). Chromosomal abnormalities can also cause miscarriage, disease, or problems in growth or development.

What is a fractured chromosome?

Description: Chromosome breakage disorders are a group of related diseases which are characterized by spontaneous chromosome breakage, immunodeficiency and predisposition to malignancy.
