Karyotype-phenotype correlations in autosomal chromosomal aberrations

Abstract

Karyotype phenotype correlation studies on the basis of clinical findings released the following consistent results. 1. Monosomy for an autosomal segment causes more and more severe alterations to the phenotype and restricts survival more than does trisomy for the same segment. The clinical pictures of monosomy versus trisomy for the same segment do not go into an opposite direction (the type-contratype approach). 2. For trisomy versus tetrasomy of a given autosomal segment, clinical pictures are principally similar, but tetrasomy lea Show more
