Mosaic Down syndrome is typically diagnosed through genetic testing If there are variances in how many copies of chromosome 21 a person has from cell to cell, a diagnosis of mosaic Down syndrome may be made Like with Trisomy 21, mosaic Down syndrome is not an inherited condition. A child with Down syndrome also may have heart defects and problems with vision and hearing How severe or mild these problems are varies from child to child Down syndrome is one of the most common genetic birth defects It affects about 1 in 800 babies Adults with Down syndrome may live about 60 years, but this can vary.

Mosaic Down syndrome is a genetic disorder, wherein an affected individual possesses two types of cell, some with 46 chromosomes, and others that contain an extra copy of the chromosome 21 The presence of an extra chromosome in some cells can manifest in several different ways, and produce a number of physical and cognitive symptoms, which are discussed in this article. Down syndrome or Trisomy 21 refers to the presence of three instead of two 21st chromosomes in each of the body’s cells This results in cognitive impairment, slightly different appearance, and risk for certain health issues or birth defects Mosaicism is a term used to describe a condition where people have different kinds of cells in the body Mosaic Down syndrome can thus be understood as.

Mosaic Down syndrome occurs when there is a combination of cells with the normal number of chromosomes (462) mixed together with those containing a third chromosome 21 (472) The cells with normal chromosomes can moderate the effect of the trisomy 21 cells and modify the effect on the patient's physical and mental development.
