The Duffy blood group is linked to the alpha-spectrin locus in a large pedigree with autosomal dominant inheritance of Charcot-Marie-Tooth disease type 1
Abstract
The alpha-spectrin locus (SPTA) on chromosome 1 maps to 1q22-q25 and alpha-spectrin specific probes detect restriction fragment length polymorphisms (RFLPs) with the endonucleases MspI and PvuII. The Duffy blood group (FY) has been mapped to the 1p21-q23 region. We found positive linkage between the alpha-spectrin and the Duffy loci with a maximal Lod score of 3.81 at theta = 0.0 using the computer program MLINK. This indicates that both loci are very closely linked and probably localized to 1q22-q23.
