The physical phenotype of Down syndrome, one of the most prevalent genetic disorders, results from an extra copy of regions q22.1 to q22.3 of chromosome 21 in cells of affected individuals. The gene coding for chromosomal protein HMG-14 is among the limited number of genes, coding for known functions, which has been mapped to this region of chromosome 21. Here the authors report a gene dosage effect on the expression of HMG-14 in both cultured cells and brain tissue samples obtained from Down syndrome patients. The putative role of HMG-14 in the structure of active chromatin raises the possibility that elevated levels of this protein may be a contributing factor in the etiology of Down syndrome.
