Somatic mosaicism is the accumulation of mutations in DNA sequence or copy number in cellular genomes after fertilization. It is a known cause of neurological disorders including developmental brain ...

Mosaicism occurs when two or more groups of cells in a person possess a different genetic makeup. As a mosaicism example, a person might possess some cells that have 46 chromosomes while other cells ...

Scientists have long speculated that mosaicism -- a biological phenomenon, in which cells within the same person have a different genetic makeup -- plays a bigger role in the transmission of rare ...

Researchers identified mosaicism as a possible factor influencing Alzheimer’s risk in adults with Down syndrome, offering new insights into amyloid biomarkers and their broader implications for the ...

(COLUMBUS, Ohio) – In most people, every cell in their body contains the same genetic information. However, sometimes people can have two or more genetically different sets of cells. This usually ...

New evidence shows that the genetic makeup of the embryo may cause the appearance of tumors in adult life. These results bear out the growing theory that some tumors may have an extremely early origin ...

In most people, every cell in their body contains the same genetic information. However, sometimes people can have two or more genetically different sets of cells. This usually happens during fetal ...

There are several predictors of IVF success. [2] Female age is probably the most important among them. With age, ovarian reserve declines, as does oocyte quality. As a result, fewer embryos are ...

One factor that limits the success of in vitro fertilization (IVF) procedures is the number of viable embryos available for implantation in the uterus. A study published November 18 in the American ...

Mosaic Down syndrome is a variant of Down syndrome. Down syndrome is a congenital (present at birth) genetic condition that occurs when a person has three copies of chromosome 21 instead of two (the ...
