摘要

The distinction between monogenic and complex diseases, once based on the possibility of identifying a clear correlation of phenotype with genotype in monogenic and not in complex diseases, is no more valid. In fact, phenotype-genotype associations can often be unpredictable even in monogenic diseases (Hartikka et al., 2004). The proteins coded by the mutant genes might display complex functions not directly related with the diseased phenotype, or may have variable organ involvement depending on which specific amino acid is substituted (Biggin et al., 2004). However, the localization of the mutated amino-acid residue is frequently poorly correlated with phenotype and different mutations are associated, in most disorders, with relatively subtle phenotypic differences.
