Why is the ptt increased for antiphospholipid syndrome? The lupus anticoagulant is one of the antibodies that binds to phospholipids in this way and frequently causes the aPTT to be prolonged. While the aPTT is used to detect clotting factor deficiencies and to monitor heparin levels, it can also be used to identify antiphospholipid syndrome.
How does antiphospholipid syndrome affect aPTT? Antiphospholipid antibodies with lupus anticoagulant activity may prolong phospholipid-dependent coagulation tests such as the activated partial thromboplastin time (aPTT) and the activated clotting time (ACT).
Why does lupus anticoagulant increase aPTT? It prolongs the APTT test, as well as several other related tests, because the lupus anticoagulant binds to phospholipids and the reagents (chemicals) used in performing the APTT test contain phospholipids. In the body phospholipids play a vital role in the blood clotting process.
How does antiphospholipid syndrome cause coagulation? Antiphospholipid (AN-te-fos-fo-LIP-id) syndrome occurs when your immune system mistakenly creates antibodies that make your blood much more likely to clot. This can cause dangerous blood clots in the legs, kidneys, lungs and brain.

Who discovered jacobsen syndrome?
Jacobsen syndrome (JS) is a contiguous gene syndrome caused by partial deletion of the long arm of chromosome 11. The condition was first described by Jacobsen in 1973 in a family with multiple members that inherited an unbalanced 11;21 translocation derived from a balanced translocation carrier parent [1].
How is down syndrome dominant or recessive?
Like cystic fibrosis, Down’s Syndrome is autosomal recessive. This means that the condition is genetic and passed down by the mother and/or the father but the condition is not shown in the parents. An autosomal recessive disorder requires two copies of the abnormal gene for the disease or trait to develop.

How early can you detect down syndrome after birth?
Diagnostic tests that can identify Down syndrome include: Chorionic villus sampling (CVS). In CVS, cells are taken from the placenta and used to analyze the fetal chromosomes. This test is typically performed in the first trimester, between 10 and 13 weeks of pregnancy.

Who discovered kallmann syndrome?
Kallmann syndrome was first described by name in a paper published in 1944 by Franz Josef Kallmann, a German-American geneticist. The link between anosmia and hypogonadism had already been noted by Spanish doctor Aureliano Maestre de San Juan in 1856.
What is the outlook prognosis for morquio syndrome?
Outlook. Long-term outcomes for children with Morquio syndrome vary from child to child. Most children with Morquio syndrome have normal intelligence. Children with spine and bone conditions can have difficulty walking and may require a wheelchair; others may be more mobile.
How does treacher collins syndrome occur?
Treacher Collins syndrome (TCS) is caused by changes ( mutations ) in any of several genes : TCOF1 (in over 80% of cases), POLR1C, or POLR1D. In a few cases, the genetic cause of the condition is unknown. These genes appear to play important roles in the early development of bones and other tissues of the face.
Is crest syndrome limited or diffuse scleroderma?
Limited scleroderma, also known as CREST syndrome, is one subtype of scleroderma — a condition whose name means “hardened skin.” The skin changes associated with limited scleroderma typically occur only in the lower arms and legs, below the elbows and knees, and sometimes affect the face and neck.

CREST syndrome is characterized by: Calcinosis: Calcium skin deposits. Raynaud’s phenomenon: A condition in which the blood vessels of the fingers and toes spasm when triggered by factors, such as cold, stress or illness. Cold, painful or numb fingers and toes result, which in severe cases may become gangrenous.

Scientists from Flinders University in Australia have identified receptors that can cause itchy skin are also found in the gut.
