Genetics

"Genes embody knowledge about their niches. Everything of fundamental significance about the phenomenon of life depends on this property, and not on replication per se."

"Humanity should study the foundations of heredity. But this will be possible only when science is liberated from superstition and limitation. Many accumulations have piled up on man. Heredity of one’s personal incarnations, heredity of the clan, heredity of one’s people, supermundane heredity, and also the many influences of accidental encounters, which imprint themselves on the psychic nature and change it. Indeed, scientists of limited mind can observe heredity only within the context of the family; in other words, within the most narrow limitations. They occasionally do observe those inherited traits that may appear even after several generations. But they cannot make the more sensitive observations, because they do not believe in reincarnation or in the Supermundane World. It is impossible to properly observe man within these narrow, ignorant limitations, but one may hope that science will free itself and will achieve true insights... The Thinker reminded, “Liberate science, hasten to remove its fetters.” (929)"

"The attitudes vary between countries, there are numerous texts for various types of biobanks, the same texts raise different interpretations in different institutions, there are new ethical opinions expressed, and mainly the novelty of questions raised by the uses of samples that are possible today, especially in genetics, and were not foreseeable at the time of sampling make the field difficult in practice."

"Modern science is proving more and more clearly that heredity plays an ever-decreasing part in the evolution of the higher creatures, that mental and moral qualities are not transmitted from parents to offspring, and that the higher qualities the more patent is this fact ‘ the child of the genius is oft-times a dolt; commonplace parents give birth to a genius."

"Most Americans still believe that there is some biological legitimacy to our socially constructed racial categories. However, our modern scientific understanding of human genetic diversity flies in the face of all of our social stereotypes."

"One prong in the approach to incorporating genetics into clinical work focuses on the parents of individuals with eating disorders. Whether the parents are involved in parent training, traditional family therapy, or other types of supportive interventions, they can be educated about genetic factors influencing eating disorders. A sensitive explanation that incorporates knowledge about complex genetic etiology (not the one gene-one disease model) and about how genes and environment interact can serve to relieve guilt in parents who have been blamed for creating the illness in their offspring (or alternatively erroneously assumed that their parenting was to blame). A genetic and biological explanation can help parents understand that their child’s resistance is not just stubbornness or deviousness, but that in his or her recovery, their child is fighting an uphill battle against his or her biology. This knowledge can empower parents to understand and can decrease frustration. Care should be taken that parents do not transform this knowledge into a new form of guilt (i.e., feeling guilty for passing on risk genes), as the roll of the genetic dice is one thing over which we have no control. Likewise, care should be taken not to allow the genetic information to impart complete absolution on parents, as parenting can always improve and positive parenting changes should also be prescribed as part of treatment."

"A question commonly posed by clinicians, families and patients alike is, how do genes work in influencing risk for eating disorders? The lay conception of genetics tends to over-emphasize the deterministic aspect of genetic risk. Modeled after Mendelian inheritance one gene-one disorder examples (e.g. Huntingtons), the misperception emerges that there is one gene for anorexia nervosa and if you have that gene you are destined to develop the condition. Clinicians are well-positioned to dispel these myths and offer more realistic albeit complicated explanations for complex inheritance patterns. By definition, eating disorders are complex traits. That means that their inheritance pattern in families does not follow traditional Mendelian patterns, and that they are influenced by multiple genetic and environmental factors of small to moderate effect. There is not one gene for anorexia nervosa or one gene for bulimia nervosa. More likely there are a number of genes that code for proteins that influence traits that index vulnerability to these disorders. Complicating the risk picture even further, these genes exist in concert with other genetic factors that may confer protection against eating disorders, along with main effects of risk and protective environments, as well as gene x environment interplay as we discuss in the following section."

"Although several decades ago there was significant debate about the influence of “nature” versus “nurture” on the development of psychological traits and outcomes, it is now generally accepted that both genes and environment interact to influence personality and behavior. However, in the clinical setting, genetic influences on clients’ presentation of their personal histories, including characteristics of their family-of-origin environment, their perceptions of stressful life events, and their experiences within their social network, are not generally viewed from a genetic-epidemiological perspective."

"The onion test is a simple reality check for anyone who thinks they can assign a function to every nucleotide in the human genome. Whatever your proposed functions are, ask yourself this question: Why does an onion need a genome that is about five times larger than ours?"

"Forms transmit their peculiarities to other forms that proceed from them, these other forms being part of their own substance, separated off to lead an independent existence. By fission, by budding, by extrusion of germs, by development of the offspring within the maternal womb, a physical continuity is preserved, every new form being derived from a preceding form and reproducing its characteristics. Science groups these facts under the name of the law of heredity, and its observations on the transmission of form are worthy of attention, and are illuminative of the workings of Nature in the phenomenal world. But it must be remembered that it applies only to the building of the physical body, into which enter the materials provided by the parents. Her more hidden workings, those workings of life without which form could not be, have received no attention, not being susceptible of physical observation, and this gap can only be filled by the teachings of the Ancient Wisdom, given by Those who of old used superphysical powers of observation, and verifiable gradually by every pupil who studies patiently in Their schools."

"Patients read enormous amounts about their illness and are often aware of the genetic research on eating disorders yet they struggle to understand what the data mean for them and the challenges they face every day during recovery. Helping patients to understand the genetic literature is a first step. Although they might not initially see its relevance to their situation, helping them map how disordered eating and temperamental traits track in their families by using techniques such as labeling family trees can provide a useful context for understanding genetic and environmental contributions to their current situation. An understanding of genetic and environmental interplay can provide them with an explanatory model for not only their illness, but also for understanding their sensitivity to the environment. It can help provide them with the motivation to acquire skills that may help buffer them from the environment and combat their biology most effectively."

"I would be quite proud to have served on the committee that designed the E. coli genome. There is, however, no way that I would admit to serving on a committee that designed the human genome. Not even a university committee could botch something that badly."
