I try, not always successfully, to read most of each week’s edition of The Economist. In the October 15th-21st science section a report Transporter of Delight, discusses new information about the genetic underpinning of happiness, and confirmed some of my biases about the biopsychosocial nature of fibromyalgia. The story reported that Jan-Emanuel De Neve and colleagues performed a rigorous case control study involving 1,939 adolescents (De Neve J-E et al, 2011). Genetic information was collected and correlated with a validated satisfaction questionnaire. They controlled for other important potentially causative factors including education, economic status, religiosity, and many others, and discovered a gene that regulates happiness, the same gene that is found in people with fibromyalgia. The magazine story is the genesis for this polemic.

A little background

Human DNA is composed of approximately 21,000 genes, distinct regions arranged in 23 pairs - one each from the mother and father. The two components of each separate gene have subtle differences of amino acid distribution, which affect their function.
These slightly different functional variants of the same gene are called alleles. The gene of interest is called 5-HTTLPR and modulates serotonin concentrations in the nervous system. This gene consists of a short and long allele, based on the number of amino acid residues in their structures - the long one produces more serotonin transporter proteins, which produce more serotonin than the shorter allele. The researchers found that individuals with long alleles and those with higher serotonin concentrations in the nervous system were statistically more likely to be very satisfied with their life, compared to individuals with short alleles (p=0.012).
Serotonin is a chemical, which is released by neurons and governs the magnitude of neural activity. Low serotonin concentrations in the central nervous system is causally linked to affective disorders (Thieme K et al, 2004; Abeles AM et al, 2007). This same alteration of the serotonergic system is a crucial factor underlying the severity and pathogenesis of FMS (Russell IJ et al 1992; Stahl SM et al, 2009).
Familial aggregation occurs in fibromyalgia. For example, among 533 first degree relatives of 78 fibromyalgia patients compared to 272 first degree relatives of 40 rheumatoid arthritis patients, the odds ratio for having fibromyalgia was 8.5 in fibromyalgia relatives versus the rheumatoid arthritis relatives (Arnold LM et al, 2004). Others have demonstrated an increased frequency of the short allele of the serotonin transporter gene 5-HTTLPR in fibromyalgia (Offenbacher M et al, 1999). In the general population, the short allele confers vulnerability to a spectrum of illnesses including anxiety disorder, depression, and bipolar disorder (Lucki I, 1998).
Furthermore, increased amygdala activation to environmental stresses such as facial expression, proven by functional magnetic resonance imaging (Hariri AR et al, 2006), and other methods (Munafo MR et al, 2008) has been linked to this same allele. The amygdala is responsible for negative interpretation of environmental stimuli; increased activation equals higher “fear factor”.....
