Abstract:
:Investigation of lymphocyte cultures from three females heterozygous for fra(X)(q27) shows widely differing proportions of early and late replicating X chromosomes having the fragile site, and suggests that the replication status of the fragile X may be related to the mental capacity of the patient. The study has utilised a sequential staining technique to reduce ascertainment bias, and evidence is presented to suggest that the expression of the fragile site is independent of the differential incorporation of BUdR into the early and late replicating X chromosomes.

HUMAN GENETICS文献大全abstract::Loss-of-function mutations in several different neuronal pathways have been related to intellectual disability (ID). Such mutations often are found on the X chromosome in males since they result in functional null alleles. So far, microdeletions at Xq24 reported in males always have been associated with a syndromic fo...
