dc.description.abstractNonsense-mediated mRNA decay (NMD) is of universal biological significance1, 2, 3. It has emerged as an important global RNA, DNA and translation regulatory pathway4. By systematically sequencing 737 genes (annotated in the Vertebrate Genome Annotation database) on the human X chromosome in 250 families with X-linked mental retardation, we identified mutations in the UPF3 regulator of nonsense transcripts homolog B (yeast) (UPF3B) leading to protein truncations in three families: two with the Lujan-Fryns phenotype5, 6 and one with the FG phenotype7. We also identified a missense mutation in another family with nonsyndromic mental retardation. Three mutations lead to the introduction of a premature termination codon and subsequent NMD of mutant UPF3B mRNA. Protein blot analysis using lymphoblastoid cell lines from affected individuals showed an absence of the UPF3B protein in two families. The UPF3B protein is an important component of the NMD surveillance machinery8, 9. Our results directly implicate abnormalities of NMD in human disease and suggest at least partial redundancy of NMD pathways.en
