Down syndrome (trisomy 21) is a genetic disorder. It includes certain birth defects, learning problems, and facial features. A child with Down syndrome also may have heart defects and problems with vision and hearing. A mother’s age at her child’s birth is the only factor linked to the risk of having a baby with Down syndrome.

Trissomia do 21 e Síndrome de Down: uma breve revisão Resumo Embora os mecanismos moleculares que causam a síndrome de Down (SD) não sejam totalmente conhecidos, a carac- Here, we demonstrate that XIST RNA induced in differentiated neural cells can trigger chromosome-wide silencing of chromosome 21 in Down syndrome patient-derived cells. Use of this tightly controlled system revealed a deficiency in differentiation of trisomic neural stem cells to neurons, correctible by inducing XIST at different stages of neurogenesis. Down syndrome is an anomaly of chromosome 21 that can cause intellectual disability, microcephaly, short stature, and characteristic facies. Diagnosis is suggested by physical anomalies and abnormal development and confirmed by cytogenetic analysis.

Background: Down syndrome (DS), characterized by an extra free chromosome 21 is the most common genetic cause for congenital malformations and learning  Down Syndrome.

It is not an inherited condition. The present case study describes an adult male with clinical signs of mild Down's syndrome (DS), who performed well at school and reached university level. A karyotype was done on a lymphocyte culture and mosaic trisomy 21 was found in 3% of the 437 cells analysed.

Trisomy 21 (Down) syndrome is associated with a 45% risk for heart malformations, a lesser risk of duodenal atresia (part of the small intestines is not developed Now, with Down Syndrome or trisomy 21, a process called nondisjunction accounts for about 95% of cases. Non-disjunction means the chromosomes don’t split apart. If the chromosomes in this first step don’t split apart, then one cell ends up with both chromosomes and the other gets none. Trisomy 21 is the most common chromosomal anomaly in humans, affecting about 5,000 babies born each year and more than 350,000 people in the United States. Also known as Down syndrome, trisomy 21 is a genetic condition caused by an extra chromosome. Most babies inherit 23 chromosomes from each parent, for a total of 46 chromosomes. Down syndrome or Down's syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21.

People with Down's syndrome are born with an extra chromosome at position 21 (trisomy 21). This can lead to learning disabilities, early onset Alzheimer's 

The stress hormone cortisol carries out some important functions in the human body, including controlling inflammation, regulating blood pressure and managing reactions to stress.
