DNA Marker D11S384 Shows Zero Recombination with the Ataxia-telangiectasia Locus in North American Families

Abstract
At the genetic locus D11S384, one probe detects a Taq1 RFLP and another detects a RFMP. In 52 pedigrees of North American A-T patients, parental haplotypes based on these two bi-allelic systems have a heterozygosity of 0·69 and a PIC of 0·64. No recombinant events between D11S384 and the A-T locus were detected in the 43 pedigrees in which this marker locus was informative.
