Maternal deletions of the centromeric domain usually result in BWS, but paternal deletions have been so far associated with normal phenotype. Here we describe a case of recurrent severe Intra-Uterine Growth Restriction (IUGR) with paternal transmission of an 11p15.5 60 kb deletion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>\n                      Chromosome microarray (CMA), PCR and DNA sequencing analyses showed that two fetuses conceived by a normal couple inherited from their father a 60 kb deletion encompassing the Imprinting Control Region of the 11p15.5 centromeric domain. The two fetuses died in utero with severe growth restriction. PCR amplification of parental DNAs indicated that the father carried the mutation in the mosaic state. DNA methylation and gene expression analyses showed that the deletion led to an imprinting alteration restricted to the centromeric domain and resulting in silencing of\n
