Note.— STR marker allele frequencies used for linkage analysis were those calculated by Généthon/Marshfield/deCODE. A gene frequency of .0001 and a penetrance of 95% were assumed for the disease locus.

^aZ values were calculated using the MLINK subprogram from the LINKAGE (5.1) package of programs.³⁴
