income countries. The session which included Prof. Zilfalil Alwi of Universiti Sains Malaysia, Dr. Castern Lederer of Cyprus Institute of Neorology and Genetics and Prof. Jacques Elion of Paris Diderot Medical School was moderated by Helen Robinson of the Human Variome Project Australian Node. The GG2020 Challenge served as a match profile of human genomics capacity and location where disease burden is highest. The project is gathering pace in parts of South East Asia, Africa and Central and South America where thalassaemias and sickle cell disease occur. HVP members are working in these areas to apply modern bio-molecular techniques to tackle these diseases.
Sir John Burn, a Board member of HVP and Professor of Clinical Genetics at Newcastle University took part in a plenary session on ‘Confidence in Science’ focused on current debates and dilemmas arising from advances in science, including those in the field of human genetics. The event was closed by President of Hungarian Academy of Sciences and President of World Science Forum, Laszlo Lavasz on 7th November 2015.

When a Geneticist Writes The Non-Genomic Action of Anabolic Androgenic Steroid (AAS) on Skeletal Muscle Fibre Type Prepared by: Dr. Muhammad Hamdi Mahmood
Universiti Malaysia Sarawak (UNIMAS), Faculty of Medicine & Health Sciences (FMHS). Skeletal Muscle Structure and Function Skeletal muscle forms the bulk of body weight (~40-50%) and its main function is to provide the force required for postural maintenance and to power all joint movements. Macroscopically, skeletal muscles can be divided into red or slow and white or fast -muscle. Red muscle is rich in myoglobin and oxidative enzymes. Its fibres express a slow form of the contractile muscle protein, myosin, which splits ATP slowly. This type of muscle is used mainly to power slow repetitive movements. In contrast, white muscle consists mainly of fibres that express forms of myosin that split ATP rapidly. They are devoid of myoglobin and are rich in glycolytic enzymes. In the body, white muscle powers activities that require large amounts of energy for short periods of time. Muscle Fibre Types Adult mammalian skeletal muscles perform a wide variety of functions ranging from the maintenance of posture to bursts of rapid movements. As a result they are composed of a mixture of fibre types that differ in their metabolic capabilities, contractile properties, ultra-structural characteristics and fatigue resistance. On the basis of these characteristics adult mammalian skeletal muscle fibres have been classified as either fast-twitch (types 2A, 2B and 2X) or slow-twitch (type 1) (Larsson et al. 1991).
Figure 1: The schematic diagram shows switching of muscle fibre types with resistance exercise the fibre type shift into a more stronger contracting fibres 1→ 2A→2X/2B. On the other hand, with endurance exercise the fibre type shift into a more fatigue resistance fibres 2X/2b→ 2A→1. Loss of type 2 fibres occurs in aging muscle.
Each of these fibre types is the product of a multi-gene programme that is tightly regulated in a fibre-type specific manner (Liu et al., 2005) and in adult muscles can be rapidly switched from one type to another depending of the activity of the motor neurones innervating them and the physiological and biochemical demands imposed upon them, this is known as muscle plasticity. Hormone is one of the several factors affecting fibre type’s composition and hence the mechanism mediating these changes are still debatable. Another major determinant of muscle fibre composition is ageing which demonstrates loss of the fast twitch fibre types (see Figure 1). Furthermore, whether these changes can be reversed by drugs/hormones such as anabolic androgenic steroids is uncertain. Anabolic Androgenic Steroid (AAS) The term AAS refers to testosterone itself, all its derivatives that are used clinically or by athletes because of their anabolic /muscle building properties as well as a number of plant products that have anabolic properties (Bhasin et al. 2005). They are all structurally related and none of them is purely anabolic. Testosterone, the principle sex hormone in males, is a C19 steroid synthesised from cholesterol in Leydig cells of the male testes. In healthy young adult men, its plasma concentration ranges from 300 to 1000ngdl-1. In plasma, most of the testosterone is bound to either albumin (~54%) or the sex hormone-binding globulin (~44%) and only 2% (~1.5-20ngdl-1) is free (Evans, 2004). In certain target tissues such as the liver, brain, prostate and pubic skin testosterone is irreversibly converted to dihydrotestosterone (DHT) by the enzyme 5α-reductase.
MyHVP Newsletter | Dec 2015 | page 4
When a Geneticist Writes Both testosterone and DHT are lipid soluble hormones and can cross the cell membrane freely. Once inside the cell, they bind the androgen receptor (AR) leading to a conformational change in its tertiary structure, the release of the chaperones bound to it and exposure of nuclear localisation sequences (Heinlein & Chang, 2002). The hormone-receptor complex then translocates into the nucleus where it binds to the hormone responsive elements on the promoter regions of its target genes. Depending on the co-activators/co-repressors recruited, the hormone-receptor complex leads to either the activation or repression of these genes (see Figure 2). This mechanism of steroid action is known as the classical or genomic pathway and because it involves gene transcription and mRNA translation, its effects usually take several hours to days to be manifested (Heinlein & Chang, 2002). In addition to their genomic actions, it is now generally accepted that steroid hormones can also exert actions that are too rapid to be explained by the classical/genomic pathway (Heinlein & Chang, 2002). These actions occur within seconds to minutes after administration of the hormone and are generally insensitive to inhibitors of the androgen receptor; suggesting that they are regulated by cellular signalling pathways involving surface membrane receptors and second messengers (see Figure 2). This mechanism of steroid action is referred to as non genomic or non classical (Losel & Wehling, 2003).
Figure 2: A schematic diagram summarising the generalised mechanism thought to underlie the genomic actions of AAS (see text for details).
Although the non classical actions of other steroid hormones such as oestrogen, progesterone and aldosterone have received a lot of attention and their actions in many tissues are well characterised (for details see review by Losel & Wehling,. 2003), little is known about the non genomic actions of steroid hormones in adult mammalian skeletal muscles. Relatively recently, in this area of research, it has been shown that DHT is the more potent AAS than testosterone. In addition, it increases the contraction force of type 2 fibre type, which is mediated through non-genomic mechanism (Hamdi & Mutungi, 2010, Hamdi & Mutungi, 2011). However whether this finding provide a clue to practically reverse muscle aging is subject to further study. MyHVP Newsletter |Dec 2015 | page 5

Figure 3: A schematic diagram summarising the generalised mechanisms thought to underlie the non-genomic actions of AAS. AAS binds to non-receptor tyrosine kinase such as c-src which activates MAPK pathway. In addition, binding of AAS to non-classical steroid receptor such as sex hormone binding globulin receptor (SHBGR) or plasma G-protein coupled receptor (GPCR) activates signal transduction cascades through activation of second messengers.

Postgraduate GENETIC COUNSELLING

enetic counselling is ‘the process of helping people understand and adapt to the medical, psychological and familial implications of genetic contributions to disease. This process integrates the following: 1. Interpretation of family and medical histories to assess the chance of disease occurrence or recurrence. 2. Education about inheritance, testing, management, prevention, resources and research. 3. Counselling to promote informed choices and adaptation to the risk or condition as defines by National Society of Genetic Counsellors.
This service is provided by a health professional known asas genetic counsellor. In certain countries, such as, the UK and the USA, genetic counsellors are deemed qualified with genetic counselling skills upon completion of a two-year Master course. During the course, they are trained to be equipped with knowledge of basic science including clinical and medical genetics, genetic risk assessment and epidemiological principles and counselling theory in order to provide services to clients and their families for adverse set of genetic or genomic indications. For countries , such as, the US, the American Board of Genetic Counselling is a regulator Board responsible for the certification of a genetic counselling training programme and licensing genetic counsellor. In the United Kingdom, the Genetic Counsellor of Regulator Board (GCRB) plays similar roles. Clinical Genetics Services in Malaysia which was established in 1994 under the purview of the Ministry of Health, provides paediatric and adult genetic services, for conditions such as metabolic conditions, haemoglobinopathies, familial cancer and reproductive genetics. However, at present, the availability of genetic counselling services provided by genetic counsellor is limited. There are only four genetic counsellors currently available in Malaysia and those who graduated from Master or postgraduate diploma in genetic counselling from the United Kingdom or Australia. Based on these figures, a ratio of one genetic counsellor per 7 million citizens (based on Malaysian population of 28 millions in 2013 statistics). At present, the Malaysian Medical Council (MMC) in its, Guideline for Medical Genetics and Genetics Service, in 2006, states that the definition of genetic counselling in Malaysia is “the provision of accurate, full and unbiased information in a caring, professional relationship that offers guidance but allows individuals and families to come to their own decisions�. Genetic counselling should essentially be provided by a medical geneticist or genetic counsellor. However, as the post of the professional genetic counsellor is not available under the Ministry of Health due to the lack of manpower, resources and budget issues, this service is provided mainly by the medical geneticists. Genetic counsellors where available serve as scientific officers or medical social workers have dual job responsibilities while fulfilling their role as genetic counsellors. Nevertheless, there are on-going efforts to create postd of genetic counsellor with formal recognition in the public health service, which will provide more specific job responsibilities as a genetic counsellor, including providing genetic counselling services to patients and families, and assisting them in coping with the implications of their genetic conditions. Universiti Kebangsaan Malaysia has taken its first step to create such post and started its Master programme in the field with its first cohort of genetic counsellors expected to graduate in 2017.
