Chromosome 6 Deletions: A chromosome 6 deletion is a rare disorder in which some of the genetic material that makes up one of the body’s 46 chromosomes – specifically chromosome 6 in this case – is missing. Like most other chromosome disorders, this increases the risk of birth defects, developmental delay and learning difficulties.

Chromosomal deletion syndromes result from loss of parts of chromosomes. They may cause severe congenital anomalies and significant intellectual and physical disability. Specific chromosomal deletion syndromes are less likely to be suspected prenatally but may be incidentally discovered at that time if karyotyping is done for other reasons.

The signs and symptoms of Chromosome 8p Deletion Syndrome may vary among affected individuals in type and severity, and include: Distinctive facial features Developmental delay Intellectual deficiency Behavioral problems Chromosome 8q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 8. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 8q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. [1] General Discussion.

A unique feature of 8p is a region of about 15 megabases that appears to have a high mutation rate. This region shows a significant divergence between human and chimpa The signs and symptoms of recombinant 8 syndrome are related to the loss of genetic material on the short arm of chromosome 8 and the presence of extra genetic material on the long arm of chromosome 8.

8p23.1 duplication syndrome is a rare genetic disorder caused by a duplication of a region from human chromosome 8. This duplication syndrome has an estimated prevalence of 1 in 64,000 births and is the reciprocal of the 8p23.1 deletion syndrome.The 8p23.1 duplication is associated with a variable phenotype including one or more of speech delay, developmental delay, mild dysmorphism, with

Se hela listan på en.wikipedia.org 2012-12-01 · 8p23.1 deletion involves a partial deletion of the short arm of chromosome 8 characterized by low birth weight, postnatal growth deficiency, mild intellectual deficit, hyperactivity, craniofacial abnormalities, and congenital heart defects. Syndromet orsakas av en förlust (deletion) av hela eller en del (ett segment) av den korta armen (p) på en av kromosomerna i kromosompar 18. Antingen har hela änden på kromosomen förlorats (terminal deletion), eller så är det en bit inuti kromosomen som försvunnit (interstitiell deletion).

Recently, we have found families where the mutation has also been inherited but different manifestations of the symptoms.
