Around 90% of Brits maintain had a flutter at least once in their lives, whether that’s a fiver on the Grand National or a pound on a fruit gadget. However, for some people, placing a bet gradually becomes more than an occasional thrill and, instead, a behavioural change that progresses to addiction.
Around 2% of people are unable to stay gambling activities that result in harm to themselves, their social network or society. ‘Gambling Disorder’ is a form of behavioural addiction with potentially severe consequences. It’s now believed that up to 70% of our gambling behaviour could be down to our entire genetic makeup, rather than responding to the thrill of the moment.
A leading testing expert, Dr Avinash Hari Narayanan (MBChB), Clinical Lead at London Medical Laboratory, says: ‘Recent changes to gaming laws will succor people who lose a lot of money in a short time, but far more work needs to be done to address this predicament. It is necessary to not only examine this from a legal perspective but to understand the factors that lead people to develop gambling disorder. This includes examining patterns in our genes that demonstrate bright links to our behaviours, traits and even susceptibilities.
‘Gambling disorder occurs when there is a repeated pattern of gambling behaviour, despite negative consequences, that takes precedence over other daily activities. This can lead to a feeling of loss of control.
‘Gambling disorder primarily appears to be an impulse control disorder, with symptoms somewhat similar to substance abuse problems. Studies indicate a likely strong genetic influence on the development of gambling behaviours. Indeed, a fascinating study of identical twins and non-identical twins, published in the journal “Addiction”, found genetic factors were responsible for approximately 70% of the inequity in their gambling behaviour. In other words, it explained why some of us can catch the occasional flutter and then forget all about it, while others become compulsive gamblers. In fact, the study found 85% of adult males’ gambling behaviour was likely to be influenced by their genes.
‘Easily available genetic tests, such as London Medical Laboratory’s novel DNA Genotype profile test, now provide not only fascinating information about our ancestry and the likely impact of certain medications on us, but they also reveal a potential likelihood to gambling disorder.
‘They work by identifying differences in those genes responsible for parts of our actions and behaviour. For example, how well finish our bodies process serotonin? Serotonin in your brain regulates your mood. It’s sometimes called your body’s natural “feel excellent” chemical. When serotonin is at normal levels, you feel better focused, more stable and happier. However, variations in one gene, HTR2A, are associated with susceptibility to mood disorders and obsessive-compulsive disorder. They also affect neuronal activity, perception, cognition and mood. These are all likely to impact on gambling disorder behaviour, either directly or indirectly.
‘One other specific gene is also now believed to play an necessary section in gambling disorder: CNR1. A 2018 study published in the journal “Frontiers of Human Neuroscience” asked the question: “Are we placing a bet by ourselves or has our DNA already made the decision for us?”. It looked at a variant in our CNR1 gene called “rs1049353” and found it had an impact on addictive behaviour and reward processing. The paper found people with this variant placed significantly larger bets than those without it. Its findings suggest that, to some extent, our high-level decision-making, even placing a bet, could be influenced by a single genetic variation.
‘Anyone who discovers that their genotype indicates that they may maintain inherited a predisposition for indulging in gambling activities can catch active steps to succor reduce risk. In fact, having an insight into our susceptibility to gambling can succor us catch preventive action. For example, easy access to gambling activities generally tends to increase its prevalence, so it is best to avoid those places where gambling is easier and those websites and apps where placing a bet could become a predicament. It’s also necessary to sustain proactively pursuing other activities, such as rekindling dilapidated hobbies. GambleAware provides further helpful information and has a 24-7 helpline.
‘Genetics does not absolutely determine predisposition to gambling. Environmental factors, such as family, social and cultural influences, and psychosocial factors, including personality traits, cognition and emotional state, also play key roles. These factors interact with genetics to shape an individual’s gambling behaviour. Genetics is only one piece of the puzzle, yet an necessary one.
‘London Medical Laboratory’s novel DNA Genotype Profile Test is a simple, at-home, saliva test kit. This once-in-a lifetime test gives over 300 reports: providing insights into nutrition, traits (such as potential addictions or gambling), fitness and health from our genetic blueprint. A single saliva sample allows each of us to know more about ourselves, so we can construct better decisions for a healthier future.
‘The saliva test can be taken at home through the post, or at one of the many drop-in clinics that offer these tests across London and nationwide in over 95 selected pharmacies and health stores.’
