MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a regulatory subunit of the SMG1 complex, which plays a critical role in nonsense-mediated mRNA decay (NMD). Binding of the encoded protein to the SMG1 complex kinase scaffold protein results in the inhibition of its kinase activity. Mutations in this gene cause a multiple congenital anomaly syndrome in human patients, characterized by brain malformation, congenital heart disease and other features. [provided by RefSeq, Jul 2016]
PHENOTYPE: Mice homozygous for a severe hypomorphic allele exhibit edema, hemorrhage, exencephaly, preaxial polydactyly, reduced size and growth, decreased mid- and hindrain size, microphthalmia, thin myocardium and atrioventricular septal defect. [provided by MGI curators]
