Abstract:
:Fluorescence in situ hybridization analysis was performed to characterize a complex pericentric inversion involving chromosome 5 in a mother and son. The mother had hypertelorism, epicanthal folds, and mild mental deficiency while the son had additional anomalies that have been observed in patients with cri-du-chat syndrome. Both individuals were found to have an identical double pericentric inversion [inv5(p15.1q31(inv5(p14q12)))]. Neither inversion breakpoint mapped near the chromosomal regions implicated in the cri-du-chat syndrome. The phenotype of the son suggests that the inversion process may have affected the expression of some of the cri-du-chat syndrome genes, suggestive of a genomic imprinting or penetrance effect.
