Translocation Down Syndrome

How you get it: Down's Syndrome is usually not inherited. The only form of this condition that can be inherited is called Translocation Down's Syndrome. Only about four percent of children that have Down's syndrome have translocation. He or she can pass on the translocation to the child, who will and up having an extra copy of Chromosome 21, which is what Down's Syndrome is.

When translocations are inherited, the mother or father has some rearranged genetic material, but no extra genetic material — this means he or she is a balanced carrier. A balanced carrier has no signs or symptoms of Down syndrome, but he or she can pass the translocation on to children, causing extra genetic material from chromosome 21.

Patau syndrome is a syndrome caused by a chromosomal abnormality, in which some or all of the cells of the body contain extra genetic material from chromosome 13. This can occur either because each cell contains a full extra copy of chromosome 13 (a disorder known as trisomy 13 or trisomy D), or because each cell contains an extra partial copy of the chromosome (i.e., Robertsonian translocation) or because of mosaic Patau syndrome.

This algorithm provides a general approach to the diagnosis and management of patients with possible spontaneous bacterial peritonitis. The clinician should suspect secondary bacterial peritonitis with any of the following: the patient has an inadequate response to antibiotics, more than one organism is isolated from culture, or at least two of the following ascitic fluid values are present (protein greater than 1 g/dL, LDH greater than ULN serum levels, and glucose less than 50 mg/dL). If…
