WebMetaphase chromosome spreads from Ubr2 -/- cells revealed a high incidence of spontaneous chromosomal gaps, indicating chromosomal fragility. These fragile sites were generally replicated late in S phase. Ubr2 -/- cells were hypersensitive to mitomycin C, a DNA cross-linking agent, but displayed normal sensitivity to gamma-irradiation. A chromosomal fragile site is a specific heritable point on a chromosome that tends to form a gap or constriction and may tend to break when the cell is exposed to partial replication stress. Based on their frequency, fragile sites are classified as "common" or "rare". To date, more than 120 fragile … See more Classification Rare fragile sites (RFSs) are classified into two sub-groups based on the compounds that elicit breakage: folate-sensitive groups (for examples, see ), and nonfolate-sensitive groups, … See more Classification Unlike RFSs, common fragile sites (CFSs) are not the result of nucleotide repeat expansion mutations. They are a part of the normal human genome and are typically stable when not under replicative stress.

WebThere were 18 individuals found to have a constitutional chromosome fragility causing an increase in break frequency. For each chromosome the breakpoint is always the same, whether it involves chromosomes from the same person, the same family, or different families.
