Presentation
Follow-up clinical management recommendations are presented that can be used when a mosaic variant is unexpectedly found in the peripheral blood. [invitae.com]
Additionally, what I have presented here is a very simplified explanation of a very complex process. [mykoweb.com]
When a person has extra or missing chromosomes in some cells and other cells with a different number of chromosomes, the phenomenon of numerical mosaicism is present. [evolvegene.com]
Each thus validated candidate gene will then be sequenced in depth in additional patients presenting a similar or overlapping clinical picture. This project will benefit from the experience of Pr. [gad-bfc.org]
Treatment is based on the signs and symptoms present in each person. [1] [2] [3] Last updated: 1/18/2015 [rarediseases.info.nih.gov]
Entire Body System
- Developmental Delay
The signs and symptoms vary but may include mild to severe intellectual disability, developmental delay, growth problems (both before and after birth), congenital heart defects, and/or abnormalities of the craniofacial (skull and face) region. [rarediseases.info.nih.gov]
Affected mosaic cases have prevalent clinical presentations such as webbed neck, developmental delay, abnormal ears, cardiac disorders, and microcephaly. [onlinelibrary.wiley.com]
Family Membership is open to those affected by a Rare Chromosome Disorder or certain Autosomal Dominant Single Gene Disorders causing as a minimum learning disability/developmental delay, among other symptoms. [rarechromo.org]

This condition is characterized by extremely weak muscle tone (hypotonia) in infancy and early childhood, intellectual disability, distinctive facial features, sparse hair, areas of unusual skin coloring (pigmentation), and other birth defects. [ghr.nlm.nih.gov]

These results indicate the presence of a weak promoter within TIME1 (“A” orientation), but detailed inspection of the nucleotide sequence did not allow its localization. [journals.plos.org]
- Short Stature
Girls are often short in stature, and they may have some emotional and learning difficulties, but most will have normal intelligence. [medicalnewstoday.com]
They had minor anomalies and/or short stature. Unusual facial appearance, MR/DD, and syndactylies were observed. [tandfonline.com]

- Fear
“Every research program is fearful of throwing away a healthy embryo, but on the other hand, mosaicism is not always a benign thing,” said Richard Scott, founder and laboratory director at Reproductive Medicine Associates of New Jersey. [nytimes.com]

Beyeler is currently establishing an independent research program aimed at identifying neural substrates of anxiety disorders. Arjun Krishnaswamy, for his essay "Building connections." [sciencemag.org]
The condition also is linked to high rates of anxiety disorders, depression, and obsessive-compulsive disorder. [verywell.com]

A diagnosis of mosaicism may cause confusion and uncertainty. A genetic counselor may help answer any questions about diagnosis and testing. There is currently no known way to prevent mosaicism. [medlineplus.gov]
And as one might expect, this proliferation of names has long been a source of confusion. We’ve been consulting with our Professional Advisory Board for a sensible naming convention. [dup15q.org]
Unfortunately, multiple terms are used to describe conditions with pigmentary mosaicism, and to avoid confusion, we suggest using the most accurate term, namely, pigmentary mosaicism. [ojrd.biomedcentral.com]

- Karyotype Abnormal
Examples of karyotypic abnormalities identified in individuals with MVA. Cytogenetics of cancer Gain of chromosomes 8 and 13 and loss of chromosomes 9 and 14 have been observed in the embryonal rhabdomyosarcoma from an individual with MVA. [atlasgeneticsoncology.org]
Treatment
Treatment Turner syndrome is a genetic condition with no cure, but treatment may help resolve issues with short stature, sexual development, and learning difficulties. [medicalnewstoday.com]
Treatment is based on the signs and symptoms present in each person. [1] [2] [3] Last updated: 1/18/2015 [rarediseases.info.nih.gov]
At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child. [urmc.rochester.edu]
Treatment will depend on the type and severity of the disorder. You may need less intense treatment if only some of the cells are abnormal. How well you do depends on which organs and tissues are affected (for example, the brain or heart). [medlineplus.gov]
Prognosis
Scientists are very enthusiastic about the discovery of genetic mosaic in brain, but Mike McConnell is cautious about the prognosis of finding remedy to mental diseases based on his findings. [aboutislam.net]
Prognosis The prognosis for an individual with MVA syndrome is based on the malformations present in the individual. [atlasgeneticsoncology.org]
In fact, most cases of mosaicism, even when detected in AF cultures, will have a good prognosis (see e.g., Hsu et al., 1997; Wallerstein et al., 2000). [what-when-how.com]
This example highlights that genetic mechanisms for a tumor phenotype may be varied, with implications for screening, diagnosis, prognosis, and therapeutic management. [genomemedicine.biomedcentral.com]

There is also evidence for the involvement of maternal cells in the etiology of neonatal or juvenile autoimmune disorders (Stevens et al., 2003). [what-when-how.com]
These parent-of-origin effects, together with the finding of paternal uniparental disomy of chromosome 11p15 in 20% of BWS cases, suggests that abnormal genomic imprinting might play an important role in the etiology of BWS. [elsevier.es]
The wide range of this result confirms the earlier mentioned and important point, that the etiology of pigmentary mosaicism is heterogeneous and complex and should not be considered distinct syndromes despite similarities in the clinical picture. [ojrd.biomedcentral.com]
