Explore mosaic Down syndrome symptoms and how copies of chromosome 21 in all cells vs. a copy of chromosome 21 in some affect people with Down syndrome.
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. It is one of the common disorders that cause lifelong disabilities especially in...

The cognitive and physical stigmata of mosaic Down syndrome (DS) are often considered to be less severe than complete trisomy-21 DS. In contrast to complete trisomy-21 DS, the ophthalmic manifestations in mosaic DS have rarely been reported. The aim of the present study is to report clinically...
In the present case dysmorphic features and developmental delay were compatible with clinical diagnosis of Down syndrome. Cytogenetic analysis demonstrated a mosaic pattern of normal cell line and a cell line with translocation 21;21[(46,xx/46,xx, T(21;21),+21]. Presence of normal cell line ...
The origin of mosaic Down Syndrome: Four cases with chromosome markers Four children, a girl and three boys, with diploid/trisomic mosaic Down syndrome were studied for the mechanism of origin of mosaics, using Q- and R-banding heteromorphisms as markers. Three mosaic subjects started as a tr...
MOSAICDOWNSYDMOMMA A real woman. A real life. Real stories. My oldest has a form of Down Syndrome thatless than 10% in the worldhave. She & I both were thrown into a life with isolation's I never thought existed in today's world. Even before this precious girl was brought into my...
The presence of a significant proportion of chromosomally abnormal cells in any such mosaic will tend to lead to a clinically expressed syndrome. The proportion of each constituent clone may vary from tissue to tissue, but is relatively stable in each individual site throughout adult life. Sex ...
Cucumber mosaic virus: Infected plants are stunted and often exhibit “shoestring syndrome,” a characteristic malformation in which the edges of the leaves fail to develop, with the leaf veins developing as long, narrow strips. Tomatoes are small and misshapen. ...
Mosaic trisomy 21 accounts for 2–4% of Down's syndrome cases, which are distinct from complete trisomy in that the former can have less severe intellectual and developmental manifestations [24]. Mosaic Turner's syndrome, also known as mosaic X loss, also manifests in a less severe phenotype...
