1.Understanding Down's Syndrome: Down's syndrome is a genetic disorder that occurs due to an abnormal number of chromosomes in a person's cells. It is specifically characterized by the presence of an extra copy of chromosome 21. 2.Chromosomal Basis: Normally, humans have 46 chromosomes arrange...

However, there could be non-disjunction of chromosomes during the process of meiosis, and as a result, one of the cells may receive an extra copy of the chromosome resulting in a condition called trisomy. One of the most common chromosome abnormality in humans is Down Syndrome, a condition ...
Down syndrome (DS; Trisomy 21) is the most common chromosomal disorder in humans. It has numerous associated neurologic phenotypes including intellectual disability, sleep apnea, seizures, behavioral problems, and dementia. With improved access to medical care, people with DS are living longer than ...
Down syndrome (DS) is the most common chromosomal abnormality in humans. DS is characterized by a number of phenotypes, including the development of Alzheimer’s disease-like pathology and immunological, hematological and cardiovascular alterations. Apoptosis or programmed cell death is physiologically inv...
Down syndrome is the most common genetic developmental disorder in humans and is caused by partial or complete triplication of human chromosome 21 (trisomy 21). It is a complex condition which results in multiple lifelong health problems, including varying degrees of intellectual disability and delays...
Down syndrome (DS), the genetic condition caused by trisomy 21, is characterized by variable cognitive impairment, immune dysregulation, dysmorphogenesis and increased prevalence of diverse co-occurring conditions. The mechanisms by which trisomy 21 causes these effects remain largely unknown. We demonstr...
Down's syndrome, named after John Langdon Down, is the most widely recognized chromosomal disorder found in humans and falls into a category of chromosomal disruptions known as trisomies; hence the other term for the condition, trisomy 21. People with Down's syndrome vary widely in their ...
DYRK1A maps to the Down syndrome critical region at 21q22. Mutations in this kinase-encoding gene have been reported to cause microcephaly associated with either intellectual disability or autism in humans. Intellectual disability accompanied by microcep
