Development of comparative genomic hybridization(CGH) technique for the study of nasopharyngeal carcinoma(NPC)
NPC is a disease in which malignant cells are formed in the tissue of
nasopharynx. It is a highly prevalent disease in Southern China and Southeast Asia
including Malaysia. CGH is a molecular cytogenetic technique which is used to identify
imbalanced genetic alterations in this malignancy. Twenty eight samples were obtained.
Out of this; twelve tumors were extracted from twelve NPC biopsies while twelve
references DNA was extracted from twelve normal controls peripheral blood. Tumor
DNA and normal DNA was labeled by nick translation method with green and red
fluorescent dyes. These were hybridized at metaphase chromosomes DNA and
counterstained with DAPL Finally, the image was captured and analyzed. Chromosomal
gains that were found in this study were 4q26, llql3-ql4, 9pl3, 8ql3-q22 and 10q22-
q26 while chromosomal losses were found at region 20p12 and 13q21-q31. We believe
this study has provided the platform for further investigations to locate possible tumorsuppressor
genes and oncogenes in our NPC patients
Global Globin Network Consensus Paper: Classification and Stratified Roadmaps for Improved Thalassaemia Care and Prevention in 32 Countries
The Global Globin Network (GGN) is a project-wide initiative of the Human Variome/Global Variome Project (HVP) focusing on haemoglobinopathies to build the capacity for genomic diagnosis, clinical services, and research in low- and middle-income countries. At present, there is no framework to evaluate the improvement of care, treatment, and prevention of thalassaemia and other haemoglobinopathies globally, despite thalassaemia being one of the most common monogenic diseases worldwide. Here, we propose a universally applicable system for evaluating and grouping countries based on qualitative indicators according to the quality of care, treatment, and prevention of haemoglobinopathies. We also apply this system to GGN countries as proof of principle. To this end, qualitative indicators were extracted from the IthaMaps database of the ITHANET portal, which allowed four groups of countries (A, B, C, and D) to be defined based on major qualitative indicators, supported by minor qualitative indicators for countries with limited resource settings and by the overall haemoglobinopathy carrier frequency for the target countries of immigration. The proposed rubrics and accumulative scores will help analyse the performance and improvement of care, treatment, and prevention of haemoglobinopathies in the GGN and beyond. Our proposed criteria complement future data collection from GGN countries to help monitor the quality of services for haemoglobinopathies, provide ongoing estimates for services and epidemiology in GGN countries, and note the contribution of the GGN to a local and global reduction of disease burden
