Submicroscopic genomic alterations in Silver–Russell syndrome and Silver–Russell-like patients

Abstract

Unexpected submicroscopic genomic events with pathogenic potential were found in three patients with molecularly unexplained SRS that was mild. The findings emphasise that SRS is heterogeneous in genetic aetiology beyond the major groups of H19 hypomethylation and maternal UPD7 and that unbiased genome-scale screens may reveal novel genotype-phenotype correlations.
