Symptoms of sugarcane mosaic virus include intense mottling throughout the laminar region of the plant, characterized by discoloration of the plants leaves, and growth stunting. [6] In maize, the infection occurs first in the youngest leaves with symptoms such as irregular, light or dark green mosaic coloring developing along the veins.
A mosaic virus is any virus that causes infected plant foliage to have a mottled appearance. Such viruses come from a variety of unrelated lineages and consequently there is no taxon that unites all mosaic viruses.
The age of diagnosis varies depending on manifestations of disease prompting reason for cytogenetic testing. Many patients are diagnosed prenatally due to fetal factors (increased nuchal fold, or abnormal levels of serum ), maternal age or abnormal ultrasounds, while others will be diagnosed postnatal due to external genital malformation.

McCune–Albright syndrome is a complex genetic disorder affecting the bone, skin and endocrine systems. It is a mosaic disease arising from somatic activating mutations in GNAS, which encodes the alpha-subunit of the G s heterotrimeric G protein.
Complete trisomy 8 causes severe abnormalities in the developing fetus and can be a cause of miscarriage. [2] [3] Complete trisomy 8 is usually a gestational lethal condition, whereas trisomy 8 mosaicism is less severe and individuals with a low proportion of affected cells may exhibit a comparatively mild range of physical abnormalities and developmental delay.

[5] [17] Likewise, a loss of the Y chromosome can result in XY/X mosaic males. [18] An example of this is one of the milder forms of Klinefelter syndrome, called 46,XY/47,XXY mosaic wherein some of the patient's cells contain XY chromosomes, and some contain XXY chromosomes. The 46/47 annotation indicates that the XY cells have the normal ...
"The pathology of Alzheimer's disease begins decades before the clinical symptoms of the disease appear," says Michal Schnaider Beeri, PhD, director of the Herbert and Jacqueline Krieger Klein ...
Individuals with PKS present prenatally or at birth with multiple birth defects.These defects include: brain atrophy, agenesis of the corpus callosum, polymicrogyria of the brain, and/or spot calcifications in the brain's lateral sulcus; deafness and/or blindness; autonomic nervous system dysfunctions such as anhidrosis, hypohidrosis, and/or episodic spells of hyperventilation interspersed ...
