Physical linkage of the gene cluster containing the LCAT gene to the DNA marker D16S124 at human chromosome region 16q22.1

摘要

Pulsed-field gel electrophoresis has been used to construct a long-range restriction map spanning more than 900 kb in the q22.1 region of human chromosome 16. The gene cluster containing the lecithinxholesterol acyl transferase (LCAT) gene is located less than 480 kb from the anonymous DNA marker D16S124 in this map. The results suggest three putative CpG islands within 125 kb, in addition to the island previously shown to be located within the gene cluster. This implies a clustering of both genes and CpG islands in this chromosomal region.
