Mutation in genes related to telomere maintenance Hoyeraal–Hreidasson syndrome [ 2 ] is a very rare multisystem X-linked recessive disorder characterized by excessively short telomeres and is considered a severe form of dyskeratosis congenita .
Genetics studies suggest the original haemochromatosis mutation arose in a single person, possibly of Celtic ethnicity, who lived 60–70 generations ago. [77] At that time, when dietary iron may have been scarcer than today, the presence of the mutant allele may have provided an evolutionary advantage by maintaining higher iron levels in the ...
Albert Stevens, a man misdiagnosed with stomach cancer, received "treatment" for his "cancer" at the U.C. San Francisco Medical Center in 1945. Dr. Joseph Gilbert Hamilton, a Manhattan Project doctor in charge of the human experiments in California, [75] had Stevens injected with Pu-238 and Pu-239 without informed consent.
Pattern hair loss (also known as androgenetic alopecia (AGA) [1]) is a hair loss condition that primarily affects the top and front of the scalp. [2] [3] In male-pattern hair loss (MPHL), the hair loss typically presents itself as either a receding front hairline, loss of hair on the crown and vertex of the scalp, or a combination of both.

Although one can inherit 13q deletion syndrome, the most common way to obtain the disease is through genetic mutations. All human chromosomes have 2 arms, the p (short) arm and the q (long) arm. They are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during ...
Although this treatment significantly decreases the serum levels of homocysteine, this treatment is not thought to improve health outcomes. [ 11 ] [ 12 ] [ 13 ] Due to the ineffectiveness of these treatments, it was no longer considered clinically useful to test for MTHFR in most cases of thrombophilia or recurrent pregnancy loss.
Human somatic variations are somatic mutations (mutations that occur in somatic cells) both at early stages of development and in adult cells. These variations can lead either to pathogenic phenotypes or not, even if their function in healthy conditions is not completely clear yet.
