Description : Mosaic variegated aneuploidy syndrome is an autosomal recessive disorder characterized
by poor growth and variable phenotypic manifestations, such as facial dysmorphism
and congenital heart defects, associated with mosaic aneuploidies resulting from defects
in cell division (summary by Snape et al., 2011). See also MVA1 (257300), caused by
mutation in the BUB1B gene (602860) on chromosome 15q15.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the 57-kD centrosomal protein gene (CEP57, 607951.0001);
Laboratory abnormalities : Mitotic lymphocyte and fibroblast cultures show mosaic variegated aneuploidy (50%)
affecting all chromosomes; Chromosomal structural abnormalities;
