ABOUT US

The Institute of Human Genetics (IHG) began in 1990 as the Medical Genetics Unit of the University of the Philippines-College of Medicine which in 1999 became one of the service and research oriented institutes of the National Institutes of Health-University of the Philippines Manila (NIH-UP). Since then, IHG expanded its services to become the largest provider of genetic services in the country - providing diagnostic, research and clinical management services in support of RA 10747 or the Rare Disease Act of the Philippines and the RA 9288 or the Newborn Screening Act of 2004.

Cytogenetics Laboratory

 

The IHG Cytogenetics Laboratory is recognized as one of the country’s leading providers of cytogenetic tests and analyses. Our lab is one of only a few in the Philippines that offers comprehensive cytogenetic services. It is a research and diagnostic laboratory specializing in the analysis of human chromosomes using a variety of techniques.

 Cytogenetics is the branch of genetics concerned with the study of chromosomes. Chromosome studies are done on dividing nucleated cells and are analyzed microscopically to identify numerical and structural abnormalities. It is still the method of choice for many types of indications for genetic testing, such as cancer diagnosis and prognosis, history of spontaneous abortions, newborn dysmorphology, prenatal diagnosis, and endocrinology disorders.

The laboratory is also known for its expertise in the use of fluorescence in-situ hybridization (FISH) for the detection of chromosomal abnormalities. FISH involves the use of DNA probes that are labeled with fluorescent dyes which are then hybridized to the target sequence within the chromosome. The fluorescence is then detected using a microscope which allows for the detection of even small amounts of genetic material such as in focal chromosome rearrangements or microdeletions. FISH analysis can be used as a diagnostic tool for a variety of indications such as cancer diagnosis, sex chromosome disorders, detection of aneuploidies, and detection of microdeletion syndromes.
