Does hypoxemia prevent brain damage in birth asphyxia?

abstract：:It has been uncovered that expansion of trinucleotide repeats in the human genome are causing a variety of genetic diseases. They are also identified in other loci that are not clearly related to particular diseases, which indicates such repeat expansion is one of the general forms of evolution occurring throughout th...
