Fine mapping of the locus for Shwachman-Diamond syndrome at 7q11, identification of shared disease haplotypes, and exclusion of TPST1 as a candidate gene

Shwachman-Diamond syndrome (SDS) is an autosomal recessive disorder characterised by exocrine pancreatic dysfunction, haematological and skeletal abnormalities. We have previously defined the SDS locus as a 2.7 cM interval spanning the centromere of chromosome 7. To facilitate additional analysis of this complex and poorly characterised region, a framework of ordered genetic markers at 7p11-q11, including six newly identified, has been...
