Synteny mapping of the genes for 21 steroid hydroxylase, alpha A crystallin, and class I bovine leukocyte antigen in cattle

DNA. 1988 Apr;7(3):143-9. doi: 10.1089/dna.1988.7.143.


Synteny mapping of the genes for bovine alpha A crystallin (CRYA-1), steroid 21 hydroxylase (21OH), and a class I major histocompatibility locus bovine leukocyte antigen (BoLA) was accomplished by Southern blot analysis of DNA from bovine-hamster hybrid somatic cells. Comparison of the distribution patterns of CRYA-1, 21OH, and BoLA sequences among the hybrid cells revealed that the genes are located on two different chromosomes in the bovine genome. CRYA-1 mapped with superoxide dismutase (SOD1 in syntenic group U10, while 21OH and BoLA were concordant with glyoxylase (GLO1) in syntenic group U21. Therefore, the syntenic array of CRYA-1, 21OH, and BoLA in cattle is different from that observed in rodents, where the genes are closely linked to each other and to GLO1, and consistent with reported linkages in man.
