Trisha Jane Lawrence was born on August 1, 2010 and weighed 31 pounds and measured 15.5 inches long. She was diagnosed with trisomy 18, but she was not expected to live very long. In this case, Trisha wasn’t able to eat because her stomach and esophagus were not connected. However, her parents stuck to God’s plan and decided against surgery to reconstruct it. Remorsefully, a year later Trisha Jane Lawrence died peacefully in her mother’s arms on August 2nd, 2011. Hence, trisomy 18 is a rare

In people with Trisomy 13, many deformities occur as a result of their genetic abnormality. One result of this disorder is a distinctive change in the subject’s appearance. Some external deformities include: a cleft lip or palate, clenched hands (with outer fingers on top of inner fingers), close-set eyes (or possibly one fused eye), decreased muscle tone, polydactyly (extra fingers or toes)(see figure 2), single palm crease (see figure 3), coloboma (having a hole, split, or cleft in the iris of

What are the signs and symptoms of this disorder? A lot of people have heard of Down Syndrome, but are unclear about what it truly means. Down Syndrome is when children are born with an extra chromosome. Specifically chromosome 21 that gets affected. During pregnancy, there are no signs that their child will have Down Syndrome. Doctors can only make educated guesses if they believe that the child will have Down Syndrome. The children that end up being born with Down Syndrome will have physical features

Acute Myeloid Leukemia is also known to be called AML and is the most common form of all acute leukemias out there. AML is generally an older person’s disease and it is uncommon in people under the age of 45 while the average age for a person with this disease is 68 years of age. AML is much more common in men than women and the risk of both male and female being diagnosed with acute myeloid leukemia is less than half of one percent. AML is rare in the diagnosis and it is estimated for the year

The first possible gene is ras1 or raspberry gene. This gene is located on the X chromosome and at 9E1-9E2 on the cytogenetic map. The location on the recombination map is unknown. The ras1 gene is a possible choice due to the dark red and orange color combination that it expresses. (Nash et al. 1994) Another gene is the Pur1 or the purplish ruby gene. This gene is located

The ABL gene from chromosome 9 joins to the BCR gene on chromosome 22, to form the BCR-ABL fusion gene. The changed chromosome 22 with the fusion gene on it is called the Philadelphia chromosome 1. Cytogenetic analysis: Used to see any chromosomal changes under the microscope. The samples are usually blood or bone marrow. This samples will be assessed and in patient with CML it will show the Philadelphia chromosome(shortened chromosome 22) normally we

Acute-myeloid-leukemia (AML) is a myeloid neoplasm which is aggressive and arrests maturation of bone marrow leading to an accumulation of immature cells of myeloblasts in bone marrow and blood. AML forms a heterogeneous and complex disease associated strongly with epigenetic and genetic changes in hematopoietic ancestors. These lead to disruptions of many signaling pathways resulting in survival proliferation, and growth of the leukemic cells. Normal HSC’s (hematopoietic-stem-cells) reside in niche

1. Define Pathophysiology: Pathophysiology may be defined as the study of function of diseased organs with application to diagnostic procedures and patient care. Pathophysiology involves the study of functional changes in the body that result from disease processes. Pathophysiology includes some aspects of pathology which refers to the laboratory study of cell and tissue changes associated with disease. 2. Define Disease: Disease may be defined as an abnormal state in which the healthy anatomy (structure)

People who have Myelodysplastic Syndrome may not experience symptoms at the beginning of the disease. However, there are three main signs that can develop and alert healthcare providers that something is wrong. One of these is a low red blood cell count, or Anemia. Most patients that have myelodysplastic syndromes exhibit this indicator when first diagnosed. A normal red blood count can vary between 4.0 and 6.1 million red blood cells per microliter of blood in the body, depending on the age
