GENETIC ABNORMALITY Meaning and
Definition
-
Genetic abnormality, also known as genetic variant or mutation, refers to a deviation or alteration in an individual's genetic material from the typically observed or expected sequence. This abnormality can occur in the DNA (deoxyribonucleic acid), which is the fundamental genetic material, or in the chromosomes, the structures that house genes. It can result from several factors including a spontaneous error during DNA replication, exposure to mutagenic agents, or inheritance from parents who possess the abnormality.
A genetic abnormality can manifest in various ways depending on the specific alteration and its location within the genome. It may cause changes in the structure or organization of genes, leading to the production of abnormal proteins, disruption of essential cellular processes, or loss of normal cellular functions. This can consequently result in a wide range of physical, physiological, or developmental abnormalities in the affected individual.
Genetic abnormalities can be classified into two broad categories: genetic variations and genetic disorders. Genetic variations are relatively common and usually do not lead to any significant adverse effects on health. They contribute to the natural variation in traits and characteristics among individuals, such as eye color or height. On the other hand, genetic disorders, resulting from more severe abnormalities, can cause significant health problems, often leading to physical or intellectual disabilities, increased susceptibility to certain diseases, or shortened lifespan.
Understanding genetic abnormalities is crucial in the field of medicine and genetic research, as it helps identify potential causes of diseases, provides insights into inheritance patterns, and aids in the development of targeted therapies or preventive measures. Genetic testing and counseling are often employed to assess and manage the risks associated with genetic abnormalities.

Etymology of GENETIC ABNORMALITY
The etymology of the term "genetic abnormality" can be broken down into the origins of its individual components.
1. Genetic: The word "genetic" stems from the noun "gene", which was coined by the Danish scientist Wilhelm Johannsen in 1905. Johannsen derived the term from the Greek word "genos", meaning "race" or "generation". "Genos" is further related to the Greek verb "gignomai", meaning "to beget" or "to bring forth".
2. Abnormality: The word "abnormality" is derived from the Latin word "abnormis", which combines the prefix "ab-" (meaning "away from" or "not") and "norma" (meaning "rule" or "pattern"). "Abnormis" implies deviation from a normal state or a departure from an established norm.
