Transition From Fish To Array Based Technique Open Up New Possibilities In The Molecular Cytogenetic
Total Articles: 44
Molecular cytogenetics plays an important role in diagnosis of various diseases. Based on the type of diseases, the diagnosis can be possible using various cytogenetic techniques such as Fluorescence In Situ Hybridization (FISH), In Situ Hybridization, Karyotyping, Banding Techniques, and others. The banding techniques have been used since past decades because of their easy accessibility and availability. However, due to its drawbacks in identifying genetic diseases at submicroscopic level, it is further modified into in situ hybridization. Currently, the FISH plays a major role in diagnosis of various diseases at genetic level using advanced molecular cytogenetic products. FISH is mainly used to detect the chromosomal aberrations such as deletion, duplication, insertion, and gene expression. It can be applicable to any specimen. Also, it is suitable for heterogeneous breakpoints or multiple translocation patterns. However, it has less sensitivity for detecting the genetic abnormality and requires expertise to interpret the results as there is a risk of getting false positive results. However, with the growing need to diagnose diseases at molecular level, array-based technologies have emerged and preferred over FISH technique.
From the past decades, various diagnostic techniques had been used for the detection of various chronic diseases. From Ancient time, the diagnosis of genetic diseases is a major concern since there were few diagnostic techniques available in the market. Instead, diagnosis was possible only when the disease showed the symptoms as most genetic diseases are hereditary and hence can be observed only when found in their children. Therefore, scientists tried to find out the less invasive techniques and found In Vitro Diagnostic (IVD) method. It uses only blood or tissue from the patients and hence reduces the susceptibility for other diseases. After the diagnosis was done using this technique, it was found that the genetic diseases are mainly due to genetic imbalance or molecular imbalance. And hence scientists tried to found new technique which is specific only for genes or molecules related to that particular disease, resulted in the emergence of molecular cytogenetics. It helps to find the cause of disease at molecular or cellular level. “Meticulous Research” in its latest publication states that, the “global market for molecular cytogenetics is expected to grow at a CAGR of 11.0% from 2017 to 2022 to reach $2,266.4 million by 2022.”
This growth is primarily driven by the increasing focus on preventive healthcare measures, increasing genetic abnormalities; growing aging population and subsequent increase in chronic diseases, increasing need to reduce mounting healthcare cost, and rising focus on clinical and research diagnosis.

The focus on preventive healthcare measures has been continuously increasing since past decade. This is mainly due to the increase in rare and genetic diseases across the world. According to the Global Genes statistics, there are about 7,000 rare diseases, out of which around 80% are of genetic origin and remain undiagnosed until 2017. There are about 350 million people affected by genetic and rare diseases in 2017 across the world. Hence, the preventive measures become an important domain in healthcare system. The preventive measures can be acquired by identifying the most promising preventing care technologies. Preventive healthcare measures can be used in form preventive tests so as to identify the current disease status of the patient. This is widely used because it determines whether the person has positive history of symptoms or showing risk of disease at a future date.
With continuous rise in the number of people affected by genetic diseases, there is lot of momentum for the preventive tests across the globe. According to World Health Organization (WHO), the preventive measures can be demonstrated by considering the Levels of prevention, Stages in the Natural History of Disease and Modes of intervention. The levels of prevention and modes of intervention make the market to grow up. The preventive measures for the genetic diseases can be considered for establishing the diagnosis of hereditary diseases, predict the probability of genetic diseases in individuals or in family, measuring clinical expression of diseases, predicting the birth of an offspring with or without genetic diseases using sophisticated molecular cytogenetics techniques.
Also, it also reduces the downstream processing costs, lowering hospitalization rate, enabling minimally invasive procedures. This trend significantly contributes to improve the health of people which in turn increase the availability of molecular and cytogenetic diagnostic products around the world.
