A CGGCT repeat inside the human BRSK2 island harbored divergent alleles in the NCD and control groups. This CGGCT repeat mainly consisted of 2- and 4-repeat alleles, of which the 4-repeat allele and its homozygosity were in excess in the control group A) and B). At the same locus, a 3-repeat was detected in one patient with VD C).
