Institute of Human Genetics
![](https://nih.upm.edu.ph/sites/default/files/ihg.png)
The Institute of Human Genetics (IHG) was created during the 1129th meeting of the UP Board of Regents on February 25, 1999 to promote health by understanding the genetic basis of common diseases in the Filipino population through diagnosis and early detection of potentially treatable genetic conditions.
The IHG is the largest provider of genetic services in the country, which consists of dedicated geneticists, physicians, nurses, dietitians, social workers, medical technicians, biochemists, chemists, biologists, and administrative support staff who are committed to bringing genomic medicine closer to Filipinos. To date, the Institute has 7 units – all of which are ISO 9001:2015- certified – providing support, research, and excellence in training, education, comprehensive patient care, counseling, and family support. IHG is the first Institute at NIH that has gained its ISO 9001: 2008 in 2015, and later migrated to ISO 9001:2015 in 2018. It has just been awarded its renewed ISO 9001:2015 certificate that is valid until 2024. It continues to be of service to the people, and at the same time offers quality service with its Quality Management System in place. :
1. The Clinical Genetics and Research Unit, since 1990, provides free comprehensive clinical evaluation, appropriate therapeutic management, and genetic counseling and dietary services to families and individuals with or at risk for a genetic or an inheritable disorder. This unit, being the service arm of the institute, looks after patients referred at the Philippine General Hospital under the Division of Clinical Genetics of the Department of Pediatrics. The unit is the technical partner of the Department of Health in its Integrated Rare Disease Management Program and assists in the implementation of the National Comprehensive Newborn Screening System.The unit is composed of three major sub-units:
1) Center for Human Genetics Services (CHGS)
2) Research and Special Projects, and
3) Education and Training. CHGS has two satellite centers in Visayas and Mindanao. The Center for Human Genetic Services are facilities that cover island wide services (Luzon, Visayas Mindanao) and facilitates comprehensive clinical evaluation, appropriate management (diagnostic and therapeutic), and genetic counseling services to families or individuals with genetic conditions. (since 2020)
2. The Cytogenetics Laboratory provides comprehensive diagnostic services for postnatal congenital and neoplastic/oncologic disorders. They also offer constitutional diagnostic services, neoplastic diagnostic services, and fluorescence in situ hybridization. (Since 1991)
3. The Newborn Screening Center-NIH is the first DOH-accredited NSC in the country and screens for 29+ metabolic and other inherited congenital disorders to prevent mental retardation and death. The NBS Center not only functions as a screening laboratory but also has a Follow Up Section in charge of short-term recall and follow up of positive screened cases. Currently, NSC-NIH receives samples from all birthing facilities in the National Capital Region (NCR), Region IV-B (MIMAROPA) and Region V (BICOL). (Since 1997).
4. The Molecular Genetics Laboratory is primarily engaged in research that aims to study the basis of common genetic diseases. Using relevant technology, its studies seek to gain knowledge that can be translated to the improvement of diagnosis and treatment of diseases that are unique and common to Filipinos. To this end, the Laboratory also offers services that will aid clinicians and health researchers in their studies, as well as patient services for the screening and diagnosis of genetic diseases, particularly disorders screened via the Expanded Newborn Screening Program of the Philippines among others. (Since 2001)
5. The Biochemical Genetics Laboratory is a specialized laboratory which provides biochemical testing and results interpretation for the diagnosis, study and clinical management of inborn errors of metabolism. The Biochemical Genetics Laboratory conducts both qualitative and quantitative analysis of biomarkers for inborn errors of metabolism based on specialized chromatographic methods such as tandem mass spectrometry (FIA-MS/MS), gas chromatography-mass spectrometry (GC-MS) and ultra high performance liquid chromatography (UPLC)
6. The Microarray Core Laboratory hosts two of the country’s microarray facilities and conducts research on ethnic population studies, pharmacogenetics, and the genetic basis of commonly prevalent diseases among Filipinos using high-throughput screening and expression profiling of candidate genes. Completed research involved the identification of some of the variants associated with the following diseases among Filipinos: hypertension, coronary artery disease and myocardial infarction, dyslipidemia, diabetes mellitus, systemic lupus erythematosus, asthma, leptospirosis and sepsis. The laboratory is also actively involved in the translation of the results of these researches into diagnostic or prognostication kits which may help aid clinicians in their care for patients with these diseases. (Since 2010).
7. The Hemoglobinopathy Confirmatory Laboratory screens newborns for inherited disorders of the hemoglobin chain which may result in anemia. (Since 2014)
Complementing the functions of these units, IHG offers the following services:
- Expanded Newborn Screening (ENBS) – screens for additional treatable disorders (hemoglobinopathies; disorders of amino acid and organic acid metabolism, fatty acid oxidation, carbohydrate metabolism, biotin metabolism; and cystic fibrosis) thereby facilitating early diagnosis and immediate proper treatment of affected newborns.
- Clinical Evaluation and Genetic Counseling – provides comprehensive clinical genetic and metabolic evaluation, dysmorphologic examination, and pre- and post-genetic counseling to patients and families at risk of an inheritable disorder.
- Diagnosis of Inborn Errors of Metabolism - the Biochemical Genetics Laboratory renders diagnostic services for inborn errors of metabolism. It offers locally available assays such as plasma acylcarnitine, plasma amino acid and urinary organic acid analyses, urine metabolic screening and also, sends out tests overseas such as urine pterins and dihydropteridine reductase deficiency (DHPR) and very long-chain fatty acids (VLCFAs) tests.
- Research - the Molecular Genetics Laboratory and the Microarray Core Laboratory does research studies on ethnic populations studies, pharmacogenetics, and susceptibility and prognostication of both infectious and non-communicable diseases.
- Molecular-based Testing - makes use of relevant molecular biology tools to study specific diseases that will improve the diagnosis, treatment, management, and prevention of specific genetic disorders.
- Chromosomal Studies - the Cytogenetics Laboratory provides routine chromosome analysis (blood, bone marrow) and fluorescence in situ hybridization (FISH) techniques for microdeletion syndromes.
- Confirmatory testing for Hemoglobinopathies - the Hemoglobinopathy Laboratory conducts confirmatory testing for newborns with positive screening for the different types of thalassemia and other hemoglobinopathies.
Aside from these services offered, the IHG maintains its productivity through the publication of its completed and initiated researches in indexed journals, such as the International Journal of Neonatal Screening, Human Genome Variation, BMJ Case Reports, the Philippine Journal of Science, and Acta Medica Philippina.
