Genetic discrimination by insurers: the public perception.
NORMA DAVIS: Good morning. Our first speaker this morning is Dr. Paul Billings who is currently at the California Pacific Medical Center, San Francisco.* He studied at Harvard, getting his M.D. and Ph.D degrees there and then went on to the University of Washington where he trained in internal medicine and medical genetics. Following that, he did a post-doctoral fellowship at David Farber Insti...
متن کاملGenetic Code as a Gray Code Revisited
In this paper we revisit the idea of relating the genetic code to a Gray code. This idea was originally fostered by Rosemary Swanson as a “unifying concept for the amino acid code”. We show that cyclic arrangements of the codons which are different from the one proposed by Swanson, but which are still based on the principle of minimal change, yield a better grouping of the amino acids by simila...

said to have an allele labeled as *2, shown on the test report as CYP2C19*2. No one in the doctor’s office— including the doctor himself—knew the significance of the asterisk. “The doctor called me and said, ‘I got this interesting value. It was CYP2C19 squared,’” Laposata says. “And I said, ‘What do you mean, squared?’ The doctor thought it was a superscript and *2 meant it was squared. I said...
متن کاملGenetic code
Is the code universal? No. Although most organisms have the same genetic code, researchers began to discover exceptions to the ‘universal’ code in 1979, and today we know of more than 15 alternative codes; each has just a few differences from the standard code, indicating common ancestry from this code. Several of these codes arose independently a number of times in evolution and are present in...
متن کاملA New Genetic Code Table
In this paper it is shown that within a Combined Genetic Code Table, realized through a combination of Watson-Crick Table and Codon Path Cube it exists, without an exception, a strict distinction between two classes of enzymes aminoacyl-tRNA synthetases, corresponding two classes of amino acids and belonging codons. By this, the distinction itself is followed by a strict balance of atom number ...
