Normal human centromeres contain large tandem arrays of โฃ-satellite DNA of varying composition and complexity. However, a new class of mitotically stable marker chromosomes which contain neocentromeres formed from genomic regions previously devoid of centromere activity was described recently. These

โฆ Synopsis
We describe an infant with trisomy of (5)(p10p13.1) resulting from a de novo marker chromosome. The marker's origin was identified by chromosome microdissection and reverse in situ hybridization. The clinical findings are compared to those of other partial and complete 5p duplications. This case further defines the critical region of 5p trisomy syndrome to proximal 5p. Am.

Linkage disequilibrium (LD) is a potentially powerful tool for the localization of disease genes for complex disorders. Most prior studies of the relationship between genetic distance and LD have examined only very short distances, focusing on the role of LD in fine-mapping and positional cloning. W
We describe a de novo trisomy 5p in a 1-year-old severely retarded boy. The complete short arm of chromosome 5 segregated as an additional marker chromosome in all metaphases. The marker was identified as 5p by conventional cytogenetic techniques (GTG, GBG, CBG) and molecular cytogenetic techniques
"When a child goes missing, his mother asks me to help. After all, she believes he was taken by a monster and that's my field of expertise. The search leads to the storm drains of Dearmont; not a good place to be when you've seen as many horror movies as I have. Turns out the monstrous kidnapper is
A 28-year-old man seems the picture of health, until he fractures his leg while skating in New York's Central Park. Within twenty-four hours of his surgical treatment he is dead. Next, a 36-year-old mother has knee surgery to repair a torn ligament in her knee - and within twenty-four hours she too
The authors report on a young girl with generalized developmental deficits originally thought to be caused by an unusual reaction to DPT vaccination. At the age of 4(1/2) years, chromosome analysis showed that the terminus of the short arm of chromosome 9 had extra material believed to originate fro
