In the Philippines, there is an urgent need to expand the clinical services for diagnosis, management and emotional support for patients with genetic conditions and their family members. Despite the lack of trained providers with specialization in genetics, public health related geneticsprograms are continuously being implemented. These address these current demands,strategic planning began in 2009 between local medical geneticists and international genetic professionals to develop the curriculum for an advanced degree in genetic counseling program. The board of regents at the University of the Philippines approved the proposed curriculum in January 2011, and training of the Philippines first cohort of genetic counseling students commenced in June 2011. The successful implementation of the MS of Genetic Counseling program will provide the opportunity to incorporate the match needed genetic counseling services in the country.

GENDISCAN study (Gene Discovery for Complex traits in Asian population of Northeast area) was designed to incorporate methodologies which enhance the power to identify genetic variations underlying complex disorders. Use of population isolates as the target population is a unique feather of this study. However, population isolates may have hidden inbreeding structures which can affect the validity of the study. To understand how this issue may affect results of GENDISCAN, we estimated inbreeding coefficients in two study populations in Mongolia. We analyzed the status of Hardy-Weinberg Equilibrium (HWE), polymorphism information contents (PIC), heterozygosity, allelic diversity, and inbreeding coefficients, using 317 and 1,044 STR (short tandem repeat) markers in Orkhontuul and Dashbalbar populations. HWE assumptions were generally met in most markers (88.6% and 94.2% respectively), and single marker PIC ranged between 0.2 and 0.9. Inbreeding coefficients were estimated to be 0.0023 and 0.0021, which are small enough to assure that conventional genetic analysis would work without any specific modification. We concluded that the population isolates used in GENDISCAN study would not present significant inflation of type I errors from inbreeding effects in its gene discovery analysis.

"Personalized medicine," the goal of which is to provide better clinical care by applying patient's own genomic information to their health care is a global challenge for the 21st century "genomic era." This is especially true in Korea, where provisions for clinical genetic services are inadequate for the existing demand, let alone future demands. Genomics-based knowledge and tools make it possible to approach each patient as a unique biological individual, which has led to a paradigm-shift in medical practice, giving it more of a predictive focus as compared with current treatment oriented approach. With recent advancements in genomics, many genetic tests, such as susceptibility genetic tests, have been developed for both rare single gene diseases and more common multifactorial diseases. Indeed, genetic tests for presymtomatic individuals and genetic tests for drug response have become widely available, and personalized medicine will face the challenge of assisting patients who use such tests to make appropriate and wise use of genetic risk assessment. A major challenge of genomic medicine lies in understanding and communicating disease risk in order to facilitate and support patients and their families in making informed decisions. Establishment of a health care system with provisions for genetic counseling as an integral part of health care service, in addition to genomic literacy of health care providers, is vital to meet this growing challenge. Realization of the promise of personalized medicine in the era of genomics for improvement of health care is dependent on further development of next generation sequencing technology and affordable sequencing test costs. Also necessary will be policy development concerning the ethical, legal and social issues of genomic medicine and an educated and ready medical community with clinical practice guidelines for genetic counseling and genetic testing.

PURPOSE: The purpose of this micro-ethnography is to examine whether science and societal changes impact family communication patterns among a convenience sample of 16 Korean women. METHODS: The authors observed family communication in the context of a new breast cancer genetic screening and diagnostic testing program to detect BRCA gene mutations in Korean women at highest risk. RESULTS: Analysis of in-depth interviews and field notes taken during participant observation illustrated that communication patterns in families vary according to a woman's position in the family. If a grandmother tests positive for a gene mutation, her daughters make decisions on her behalf; they open and maintain the communication channel among family members. If a housewife is diagnosed with cancer and a genetic mutation, she immediately consults her husband and her sisters. The husband creates an open communication channel between his wife, his parents and his siblings. As a result, a woman's cancer is a concern for the whole family not merely a woman's secret or crisis. CONCLUSION: Cultural differences are important to consider when designing new genetic service programs in different countries.

Although bipolar disorder is highly heritable, the identification of specific genetic variations is limited because of the complex traits underlying the disorder. We performed a genome-wide association study of bipolar disorder using a subphenotype that shows hypersomnia symptom during a major depressive episode. We investigated a total of 2,191 cases, 1,434 controls, and 703,012 single nucleotide polymorphisms (SNPs) in the merged samples obtained from the Translational Genomics Institute and the Genetic Association Information Network. The gene emerging as the most significant by statistical analysis was rs1553441 (odds ratio=0.4093; p=1.20x10-5; Permuted p=6.0x10-6). However, the 5x0-8 threshold for statistical significance required in a genome-wide association study was not achieved. The functional enrichment pathway analysis showed significant enrichments in the adhesion, development-related, synaptic transmission-related, and cell recognition-related pathways. For further evaluation, each gene of the enriched pathways was reviewed and matched with genes that were suggested to be associated with psychiatric disorders by previous genetic studies. We found that the cadherin 13 and hypocretin (orexin) receptor 2 genes may be involved in the hypersomnia symptom during a major depressive episode of bipolar disorder.

PURPOSE: The purpose of this review article is to introduce how the Korean Society of Genetic Nursing (KSGN) has evolved and tried to translate genomic knowledge to nursing practice, and then to suggest the future role of genetic nurses in Korea. METHODS: A literature review was performed and the current status of genetic counselling in Korea was explored. Then the educational and clinical experiences of the authors were incorporated. Finally, the main activities of Korean nursing for genetics were identified. RESULTS: Two types of genetic counsellor certification have been issued in Korea: one is issued by the Korean Society of Genetic Medicine, another by the Korean Society of Breast Cancer since June 2011. A few Korean nursing researchers have continuously performed research related to genetic nursing and undertook several research projects funded by the government since 2003. In February 2011, KSGN was established and is now trying to establish further international networks. CONCLUSION: Nursing genetic experts should be trained to integrate all specialties for genetic counselling, so they can provide holistic genetic services including ethical, legal, and social issues (ELSI).

OBJECTIVETo set up thalassemia population intervention model in order to decrease the birth of thalassemia major, relying on population and family planning service system.

METHODSPregnant women and their husbands were educated about thalassemia, and participated in screening and prenatal diagnosis if the couple were carriers of thalassemia in the areas of Huangpu, Panyu, Zengcheng and Tianhe districts of Guangzhou.

RESULTSThe network of thalassemia intervention mainly dependent on family planning service system was set up in these regions. A total of 10 695 families participated in thalassemia screening and 16 thalassemia major fetuses were diagnosed in the last two years. No one was thalassemia major in the 8360 newborn.

CONCLUSIONThalassemia population intervention model was set up relying on family planning service system and it significantly decreased the birth of thalassemia major.

OBJECTIVES: The genetic facotrs have been suggested for the etiology of mood disorders but the mode of inheritance is complex. Increased severity and an earlier onset of the bipolar and major depressive disorder over generations within families(Anticipation) were reported. In order to test the hypothesis that trinucleotide repeat expansions underlie the genetic basis of Bipolar and major depressive disorders, we have analyzed the extent of CAG reapeats in genomic DNA from mood disorder patients. METHODS: 55 bipolar disorder, 67 major depressive disorder patients were recruited according to the DSM-III-R criteria. 89 normal controls were recruited from the medical personnel, students and the visitors to the health services center who had no history of psychiatric illness and show normal profile of MMPI. The genomic DNA of patients and controls was analyzed by use of the(CTG) 17 oligonucleotide and the repeat expansion detection(RED) method. The Mann-Whitney U test was used to compare the distribution of the number of CAG repeats among the groups. RESULTS: when the bipolar disorder, major depressive disorder patients were compared with the control group, no significant differences were observed. CONCLUSION: Our results do not support the hypothesis that expanding CAG repeats are causing the observed genetic anticipation in bipolar disorders and major depressive disorders.

Varicella-Zoster virus (VZV) is the causative agent of chickenpox in children. It also causes herpes zoster in old or immunocompromised people. For effective control of VZV, live attenuated vaccine (Oka strain) was developed in 1974 and has been used worldwidely. This vaccine is indicated when VZV infection can be fatal, such as leukemia, with favorable success. Recently, routine usage of VZV vaccine for general young population was proposed. However, general use of vaccine requires prior epidemiological study of wild strains prevailing in the target population. In this regard, we investigated the antigenic and genetic variations, if any, between Oka strain and wild strains isolated in Korea. Six wild strains of VZV isolated from zoster patients in Korea, Ellen (the labaratory-adapted strain) and Oka (vaccine) strains were cultivated in Vero cells. After the VZV-infected Vero cells were stained with specific monoclonal antibody panel, the immunofluorescent patterns were compared. The VZV-infected Vero cells were also extracted after metabolic labelling to be immunoprecipitated with the monoclonal antibodies. However, the patterns of immunofluorescent staining and immunoprecipitation did not show any antigenic difference among wild strains and vaccine or standard strain. When the VZV gene was amplified by polymerase chain reaction using primer VZV 115953 and 116605, and the PCR products were cleaved by restriction enzymes (Taq I, Bl II, and Hpa II), two kinds of restriction patterns were observed. These results suggested that antigenic variation was not common among wild strains of VZV isolated in Korea and between vaccine strain. But the different restriction patterns implied potential antigenic variation.
