Alu elements comprise >10% of the human genome. We have used a computational biology approach to analyze the human genomic DNA sequence databases to determine the impact of gene conversion on the sequence diversity of recently integrated Alu elements and to identify Alu elements that were potentially retroposition competent. We analyzed 269 Alu Ya5 elements(More)
Fibroblast growth factors were first characterized twenty years ago as mitogens of cultured fibroblasts. Despite a wealth of data from experiments in vitro, insights have begun to emerge only recently on the normal function of these growth factors in mice and humans, as a result of studies of natural and experimental mutations in the factors and their(More)
The Human Phenotype Ontology (HPO) project, available at http://www.human-phenotype-ontology.org, provides a structured, comprehensive and well-defined set of 10,088 classes (terms) describing human phenotypic abnormalities and 13,326 subclass relations between the HPO classes. In addition we have developed logical definitions for 46% of all HPO classes(More)
Dominantly acting mutations of the fibroblast growth factor (FGF) receptor 2 (FGFR2) gene have been implicated in various craniosynostosis syndromes. Apert syndrome, characterized in addition by syndactyly of the limbs, involves specific mutations at two adjacent residues, Ser252Trp and Pro253Arg, predicted to lie in the linker region between IgII and IgIII(More)
Genes mutated in congenital malformation syndromes are frequently implicated in oncogenesis, but the causative germline and somatic mutations occur in separate cells at different times of an organism's life. Here we unify these processes to a single cellular event for mutations arising in male germ cells that show a paternal age effect. Screening of 30(More)
The mouse mutant Doublefoot (Dbf) shows preaxial polydactyly with 6-9 triphalangeal digits in all four limbs and additional abnormalities including a broadened skull, hydrocephalus, and a thickened, kinked tail. The autopod undergoes a characteristic expansion between late embryonic day (E) 10.5 and E11.5, following the onset of ectopic Indian hedgehog(More)
The heterozygous Pro250Arg substitution mutation in fibroblast growth factor receptor 3 (FGFR3), which increases ligand-dependent signalling, is the most common genetic cause of craniosynostosis in humans and defines Muenke syndrome. Since FGF signalling plays dosage-sensitive roles in the differentiation of the auditory sensory epithelium, we evaluated(More)
TCF12-related craniosynostosis can be caused by small heterozygous loss-of-function mutations in TCF12. Large intragenic rearrangements, however, have not been described yet. Here, we present the identification of four large rearrangements in TCF12 causing TCF12-related craniosynostosis. Whole-genome sequencing was applied on the DNA of 18 index cases with(More)
Observed mutation rates in humans appear higher in male than female gametes and often increase with paternal age. This bias, usually attributed to the accumulation of replication errors or inefficient repair processes, has been difficult to study directly. Here, we describe a sensitive method to quantify substitutions at nucleotide 755 of the fibroblast(More)
BACKGROUND The C749G (Pro250Arg) mutation in the gene for fibroblast growth factor receptor 3 (FGFR3) has been found in patients with various types of craniosynostosis. We aimed to find out the proportion of cases of apparently non-syndromic coronal craniosynostosis attributable to this mutation. METHODS We studied 26 patients with coronal(More)
