ring chromosome उदाहरण वाक्य
उदाहरण वाक्य
- This supernumerary ring 20 can cause multiple anomalies but no epilepsy, and this resulting syndrome should be differentiated from ring chromosome 20 syndrome.
- CGH is only able to detect unbalanced inversions or ring chromosomes do not affect copy number, which is what is detected by CGH technologies.
- A similar association between a ring chromosome and an autosomal-dominant disease has been reported for ring 17 chromosome and Miller-Dieker syndrome.
- Although not discussed explicitly in relation to neocentromeres, it is worth noting that the breakage-fusion-bridge cycle involves ring chromosomes too.
- Complex rearrangements, including segmental microdeletions and microduplications, have been seen in numerous ring chromosomes, providing important clues regarding the mechanisms of their formation.
- Ring chromosomes were discovered from their unusual frequencies of recombination in an attached-X stock, which revealed a circularized X-chromosome upon cytological examination.
- Since chromosomal analysis or karyotype testing is not a routine investigation for patients with epilepsy, the diagnosis of ring chromosome 20 syndrome is typically delayed or unrecognized.
- In most individuals with ring chromosome 20 syndrome, a certain percentage have two normal chromosome 20s and the remainder have one normal and one ring 20 chromosome.
- If it occurs during embryonic growth the ring chromosome may be present in only some of a person's cells ( i . e . Mosaicism ).
- Perhaps further studying of ring chromosomes and diseases, from the perspective of neocentromere formation, may shed light on mechanisms of tumor formation due to chromosome abnormalities.
