ring chromosome

A circular structure called ring chromosome 7 is also possible.

The recurrence risk for ring chromosome 20 syndrome is very low.

As all cases of ring chromosome 20 syndrome are not the same, individuals may respond differently to treatment.

Ring Chromosome 20 syndrome is thought to be an underdiagnosed condition.

There are no published reports on the use of the ketogenic diet in patients with ring chromosome 20 syndrome.

Ring chromosome 14 syndrome is almost never inherited.

He discovered the ring chromosome that proved the abnormal breeding habits of the oenothera.

Ring chromosome 14 syndrome is a very rare human chromosome abnormality.

A ring chromosome occurs when both ends of a broken chromosome are reunited.

A ring chromosome is a chromosome whose arms have fused together to form a ring.

Ring chromosomes were first discovered by Lilian Vaughan Morgan in 1926.

If it occurs during embryonic growth the ring chromosome may be present in only some of a person's cells (i.e. Mosaicism).

Isochromosome X or ring chromosome X on the other hand are formed equally often by both parents.

Therefore, some gene loss from the terminal segment could be responsible for the manifestation of epilepsy in ring chromosome 20 syndrome.

As chromosomes occur in pairs, the affected individual has one normal chromosome and the other replaced by a ring chromosome.

Through her work with X-ray-mutagenized maize, she identified ring chromosomes, which form when the ends of a single chromosome fuse together after radiation damage.

Ring chromosomes may form in cells following genetic damage by mutagens like radiation, but they may also arise spontaneously during development.

Newer array technology will not detect the ring chromosome and the standard metaphase chromosome analysis has been recommended.

Chromosomal ( balanced rearrangements & Ring chromosome)

It is theorized that deletions in these regions from the ringed chromosome may lead to epilepsy in affected patient.

Because of the possibility that not all cells carry the ring chromosome the karyotype analysis should examine a sufficient number of cells.

Limited data is available for the long-term prognosis of ring chromosome 20 syndrome since only over 60 patients with this syndrome have been reported in published literature.

Lilan Morgan's second major contribution to the Drosophila genetic toolkit was the dsicovery of ring chromosomes.

Complex rearrangements including segmental microdeletions and microduplications have been seen in numerous ring chromosomes providing important clues regarding the mechanisms of their formation.
