The average IQ of a young adult with Down syndrome is 50, equivalent to the mental ability of an 8- or 9-year.
Mosaic Down Syndrome. When a baby is born with Down syndrome, the healthcare provider takes a blood sample to do a chromosome study. Mosaicism or mosaic Down syndrome is diagnosed when there is a mixture of two types of cells. Some have the usual 46 chromosomes and some have 47. Those cells with 47 chromosomes have an extra chromosome 21 Mosaic down syndrome is a common genetic disorder. The syndrome is related to excessive cell division which causes extra genetic material in Chromosome 21. The genetic disorder varies from person to person and severity.

According to Stanford Children's Health, this can lead to vastly different presentations of symptoms as the concentration of trisomatic cells varies from one type of. Animal models of Down syndrome (DS), trisomic for human chromosome 21 (HSA21) genes or orthologs, provide insights into better understanding and treatment options. The only existing transchromosomic (Tc) mouse DS model, Tc1, carries a HSA21 with over 50 protein coding genes (PCGs) disrupted. Tc1 is mosaic, compromising interpretation of results Almost all Down syndrome cases result from complete trisomy 21. 1,2,3; Mosaic trisomy 21. Not every cell in the body is exactly the same.
