Somatic mutations can presumably occur at any time, but the majority are said to be phenotypically silent, if, for instance, the mutation is in a non-coding part of the genome, or a gene that is not expressed in the particular cell. The dna sequence of a gene can be altered in a number of ways gene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins. My hope is that a better understanding of the genetics and mechanisms of transgender and gender-diverse experiences will lead to greater acceptance and celebration of difference.

Several possible and potentially overlapping genetic mechanisms have been suggested to explain differences in life span between genders, including asymmetric inheritance of sex chromosomes, differences in physiology, maternal effects, and sex-specific selective pressures. A mutation is a result of a spontaneous mutating or a change of the original gene during the ovum or sperm formation so that in the first generation the offspring receives a gene that is not part of the parents genetic makeup.
