Research report: Frequencies of mica gene polymorphism: a comparison between Indonesians on Bacan Island and suburban Japanese.

MHC class I chain related gene A (MICA) is located near the HLA-B gene on the short arm of human chromosome 6. In the transmembrane (TM) of region of MICA, there is a trinucleotide repeat (GCT/AGC) microsatellite polymorphism in exon 5. Five alleles with 4, 5, 6 and 9 repetitions or 5 repetitions with 1 additional nucleotide insertion (GGCT) are identified and they were named A4, A5, A5.
