The predicted binding sequence for PRDM9 major A-allele is CCGCCGTNNCCNC. The values indicted under the columns labelled cases and controls represent the number of heterozygous carriers of the major A-allele. The minor allele for these samples and its predicted binding-sequence is indicated.

*

The L20 PRDM9 ZF allele had >100 predicted binding sequences on 21q.

**

Samples heterozygous for the major A-allele that contain a minor allele that has a predicted binding sequence identical to the PRDM9 major-A-Allele. These alleles have not been previously reported by previous studies.

***

The O2 and C alleles had no predicted binding sequences on 21q.

****

Samples heterozygous for the major A-allele that contain a minor allele that has a predicted binding sequence identical to the PRDM9 L24 allele.
