Genetic diversity at the FMR1 locus in the Indonesian population

We report an analysis of allelic diversity at short tandem repeat polymorph isms within the fragile XA locus in 1069 male volunteers from twelve Indone sian sub-populations. An odd numbered allele of DXS548 was found at high fr equency in all Indonesian populations. Greater allelic diversity was identi fied at the loci under study than has been previously reported for an Asian population. These differences distinguish the Indonesian population from a ll previously reported Asian, European and Africas populations. A high freq uency of small premutation alleles, 4/120 (3.3%, 95% CI 0.9-8.3%), was iden tified in the Moluccan population of Hiri Island.
