I'm sorry but I don't see what the question is.  As  I understand it,
pleiotropy simply means that the causative mutation produces a set of
(apparently) unrelated phenotypic effects. As long as any or all of these
phenotypes can be reasonably reliably scored, an informative pedigree can
be tested for evidence of linkage either between these phenotypes or
between 1 or more of these phenotypes and any other polymorphic locus/loci
segregating in the pedigree.
