Although the resolution of linkage, represented by the density of the “no-calls”, is not as powerful as SNP-genotyping linkage, autozygosity mapping has previously been used to precisely map two novel PCD-loci LRRC6 and CCDC103 genes in UK-Pakistani populations [26,27] and to identify a novel PCD gene, CCNO, that is associated with oligocilia and absence of situs abnormalities in a multiplex Kuwaiti family with four PCD-affected individuals [18]. This evidence concerns the gene DNAAF19 and primary ciliary dyskinesia.
