Trisomy 13 Trisomy 13‚ also known as Patau Syndrome‚ is a chromosomal abnormality where an individual has an extra chromosome 13. Trisomy 13 was first recognized by Patau and his colleagues in 1960 (Matthews‚ 1999). It affects approximately 1 in 12‚000 births and is the least common of the trisomy syndromes‚ after trisomy 18 and trisomy 21 (Down syndrome). An abnormality of the chromosome occurs when mitosis or meiosis does not happen correctly. During mitosis‚ when the cells are dividing

Abstract Down syndrome‚ also known as trisomy 21‚ is the most common chromosome abnormality in humans and it occurs in all races. Approximately 1 of every 691 babies born in the United States each year is born with this genetic condition. Because people with Down syndrome have extra copies of genes on chromosome 21‚ the course of normal development is disrupted and this leads to the distinctive physical characteristics and other health issues that are associated with this syndrome. With appropriate

syndrome (Trisomy 21) Down syndrome is a genetic disorder that occurs when an individual has an extra chromosome 21 in them. Down syndrome can also be referred to as ‘Trisomy 21’. An English physician named John Landon Down first discovered Down syndrome back in 1862. This genetic disorder has been around since the 16th century and possibly even longer. The treatments for Down syndrome are not distinct as it depends on how severe the Down syndrome is. Down syndrome or Trisomy 21 was discovered

There are three types of Down syndrome‚ and it includes Trisomy 21‚ Mosaicism and translocation. This research paper will describe Down syndrome‚ characteristics‚ and causes. Children with Down syndrome experience hearing loss‚ but no research has been done to investigate the impact it has on speech and language development. I’ve learned that individuals with Down syndrome are people too and deserve to be treated as we like we like to be treated. Throughout the semester‚ we have learned how words

If either of these gametes unites with another during fertilization‚ the result is aneuploidy (abnormal chromosome number) • A trisomic cell has one extra chromosome (2n +1) = example: trisomy 21. (Polyploidy refers to the condition of having three homologous chromosomes rather then two) • A monosomic cell has one missing chromosome (2n - 1) = usually lethal except for one known in humans: Turner’s syndrome (monosomy XO).

Victoria Haskins Biology Honors Mr. Kelly March 6th‚ 2017 Edwards Syndrome Edwards syndrome‚ also known as Trisomy 18‚ is a condition caused by a mistake in meiotic cell division resulting in an extra chromosome 18 in a developing baby (Source 1). This condition disrupts normal development‚ potentially fatally‚ even before birth (Source 1). Major characteristics of the disorder include a delay in growth‚ a low birth weight‚ and other major medical complications (Source 1‚ Source 3). Professor of

Research has shown that most babies with Trisomy 13 do not even live to be a year old. The rare percentage of babies that live over a year have severe defects and do not live a long‚ sustainable life. I want my child to have the highest quality of life possible. I would never want to bring a child into the world to have it suffer. Trisomy 13 guarantees
