What is trisomy 8 syndrome?

What is the 6th chromosome?
Chromosome 6 spans more than 170 million base pairs (the building material of DNA) and represents between 5.5 and 6% of the total DNA in cells. It contains the Major Histocompatibility Complex, which contains over 100 genes related to the immune response, and plays a vital role in organ transplantation.
Do trisomy 13 babies suffer?
Patau’s syndrome (trisomy 13) is a rare condition, associated with high mortality, a range of congenital abnormalities, and severe physical and cognitive impairment. Many affected pregnancies will miscarry, and most babies born with the condition will not survive more than a few days or weeks.

Is there such a thing as trisomy 5q?
This chromosome abnormality is most commonly associated with the myelodysplastic syndrome. It should not be confused with “partial trisomy 5q”, though both conditions have been observed in the same family. This should not be confused with the germ line cri du chat (5p deletion) syndrome which is a deletion of the short arm of the 5th chromosome.
What causes chromosome 15, Distal trisomy 15q-nord?
The range and severity of symptoms and physical findings may vary from case to case, depending upon the length and location of the duplicated portion of chromosome 15q. In most cases, Chromosome 15, Distal Trisomy 15q is due to a chromosomal balanced translocation in one of the parents.
What do you need to know about chromosome 5q?

What are the symptoms of trisomy 15q25-qter?
Signs & Symptoms. Such feeding and swallowing difficulties may result in or contribute to an affected infant’s failure to grow or gain weight at the expected rate (failure to thrive). However, in certain rare cases (i.e., trisomy 15q25-qter), affected individuals may exhibit abnormally tall stature.
