All our genetic information is contained in the cells of our body. Cook PJ, Gray JE, Brack RA, Robson EB, Howlett RM. What is a chromosome?

1970 Apr; 119 (4):370–373. The formation of ring chromosome 13 may arise during … Gerald PS, Warner S, Singer JD, Corcoran PA, Umansky I. Am J Dis Child. Ann Hum Genet. 1969 Oct; 33 (2):125–136. 1984 Jun;21(3):233. doi: 10.1136/jmg.21.3.233. Data on haptoglobin and the D group chromosomes. Ring chromosome 13 and 47, XYY are relatively rare syndromes in the human genome, respectively. An analysis of these cases together with those in the literature indicates that the syndrome forms a continuous spectrum, and no further taxonomic subdivision is possible at this stage of knowledge. 1967 Feb; 70 (2):172–179. When a ring forms, there may be missing genes where the chromosome's ends fuse together. GERMAN J. To best the best of our knowledge, the co-existence of these two chromosomal abnormalities in same individual has not previously been reported and their genetic mechanisms are considered to be independent of each other. Ring 13 Ring chromosome 13 is a rare genetic condition caused by having an abnormal chromosome 13 that forms a ring. The clinical limits of this syndrome can now be defined. Ring chromosome 13 is a rare chromosome abnormality in which the ends of chromosome 13 join together to form a ring shape. Ring chromosome D (13). A study of the ring chromosome 13 syndrome is presented with detailed clinical and cytogenetic features of three new unrelated cases.

A ring D chromosome and anomalous inheritance of haptoglobin type.

Therefore, the severity and symptoms associated with ring chromosome 13 vary from person to person, depending on the number of genes, and specific … Ring (13),t(2;6) Associated With Familial Fragile (16) Ring (13),t(2;6) Associated With Familial Fragile (16) J Med Genet. The genetic material that contains this information is the DNA, tightly coiled and forming a number of rod-like structures called chromosomes. …
