Distal trisomy 10q is a rare chromosomal disorder that causes physical defects and intellectual disability. It occurs when the distal part of the long arm of chromosome 10 is present three times instead of two.
A comprehensive list of over 6,000 known genetic disorders in humans, with their chromosome or gene involvement, type of mutation, and prevalence. The most common genetic disorders include color blindness, cystic fibrosis, hemophilia, sickle cell disease, and Tay–Sachs disease.
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 ...
Aneuploidy is the presence of an abnormal number of chromosomes in a cell, which can cause genetic disorders or cancer. Learn about the mechanisms, types and effects of aneuploidy, and how it differs from euploidy and mosaicism.
Patau syndrome is a genetic disorder caused by an extra copy of chromosome 13 in some or all of the body's cells. It affects about 1 in 10,000 to 1 in 21,700 live births and causes multiple and complex organ defects, intellectual disability, and a poor prognosis.
Learn about the types, causes, and effects of chromosomal abnormalities, which are missing, extra, or irregular portions of chromosomal DNA. Find out how they are detected, inherited, and related to cancer and other disorders.
Trisomy 21, an extra copy of the 21st chromosome, is responsible for causing Down syndrome, and the mouse chromosome 16 closely resembles human chromosome 21. [1] In 1979, trisomy of the mouse chromosome 16 (Ts16) initially showed potential to be a model organism for human Down syndrome. [2]
Trisomy is a chromosomal abnormality that occurs when a cell has three copies of a chromosome instead of two. Learn about the different types of trisomy, their causes, effects and examples in humans and other organisms.
