BACKGROUND Silver-Russell syndrome (SRS) is characterised by intrauterine growth restriction, poor postnatal growth, relative macrocephaly, triangular face and asymmetry. Maternal uniparental disomy (mUPD) of chromosome 7 and hypomethylation of the imprinting control region (ICR) 1 on chromosome 11p15 are found in 5-10% and up to 60% of patients with SRS,(More)
The Zic genes are the vertebrate homologues of the Drosophila Odd-paired gene. Mutations in two of these genes are associated with human congenital genetic disorders. Mutation of human and mouse Zic2 is associated with holoprosencephaly which is caused by a defect of ventral forebrain development and mutation of human and mouse Zic3 is associated with a(More)
Angelman syndrome (AS) and Prader-Willi syndrome (PWS) are caused by genetic and epigenetic mutations of the imprinted gene cluster on chromosome 15q13. Although the imprinting mutations causing PWS and AS are essentially opposite in nature, remarkably, a small number of patients have been reported with clinical features of PWS but epigenetic mutations(More)
Monosomy of the human chromosome 6p terminal region results in a variety of congenital malformations that include brain, craniofacial, and organogenesis abnormalities. To examine the genetic basis of these phenotypes, we have carried out an unbiased functional analysis of the syntenic region of the mouse genome (proximal Mmu13). A genetic screen for(More)
BACKGROUND Germline mis-sense mutations in the DNA-binding domain of the p63 gene have recently been established as the molecular basis for the autosomal dominant EEC (Ectrodactyly, Ectodermal dysplasia, Clefting) syndrome. OBJECTIVES To examine genomic DNA from a 36-year-old woman, her 58-year-old father and her 11-year-old son, all with the EEC(More)
