FRAGILE SITE Meaning and
Definition
-
A fragile site refers to a specific region within a chromosome that is structurally unstable and prone to developing gaps or breaks under certain conditions. These sites are characterized by their inherent susceptibility to chromosomal rearrangements, leading to potential genetic instability. Fragile sites are typically identified through laboratory procedures, such as staining or molecular methods, which help reveal structural and functional abnormalities in chromosomes.
When the DNA sequence within a fragile site becomes compromised or disrupted, it can result in various genetic disorders or diseases. Fragile sites are often associated with specific, inherited conditions, such as Fragile X syndrome, which is characterized by intellectual disabilities and other developmental impairments. Other diseases linked to fragile sites include certain types of cancer and immune system deficiencies.
The fragility of these sites can be induced or exacerbated by external factors, such as exposure to chemicals and radiation. They may also be influenced by internal genetic factors, such as variations in DNA sequence length or the presence of repetitive DNA sequences. When fragile sites are prone to breakage, it can lead to chromosomal abnormalities and the loss or rearrangement of genetic material.
Understanding and identifying fragile sites is crucial in clinical genetics and genetic research. Researchers study these sites to gain insights into the mechanisms of genetic instability, congenital disorders, and disease susceptibility. Additionally, fragile sites can be utilized as diagnostic tools for detecting certain genetic conditions, aiding in prenatal and genetic counseling.

Etymology of FRAGILE SITE
The term "fragile site" is derived from the combination of two words: "fragile" and "site".
1. Fragile: This word comes from the Latin word "fragilis", which means "easily broken" or "brittle". It entered the English language in the early 17th century.
2. Site: This word has its origins in the Latin word "situs", which means "position" or "place". It was first used in English in the mid-14th century.
When combined, the term "fragile site" refers to a specific region on a chromosome that is susceptible to breakage or rearrangements. These sites are named so because they exhibit a tendency to easily break or become unstably mutated under certain conditions or genetic factors.
