Huntington disease (HD) is associated with abnormal expansions of a CAG repeat close to the 5' end of the IT15 gene. We have assembled a set of 293 HD subjects whose ages of onset were known and sized their HD CAG repeats. These repeats accounted for 69% of the variance of age of onset when we used the most parsimonious model, which relates the logarithm of(More)
Predictive testing by means of gene probes was offered to 110 adults at risk of Huntington's disease (HD). A further 91 individuals spontaneously sought predictive testing. Acceptance rates were highest (85.1%) amongst 47 individuals who spontaneously sought testing and were referred from outside the region, and lowest (15.5%) among the 110 invited to(More)
Extensive knowledge of microbial metabolism has been earned through more than a century of reductionist study. There is now basic understanding of how cultivated bacteria transduce the chemical energy of a growth substrate into the work and biosynthetic processes that underlie both survival and replication. This includes an appreciation that microorganisms(More)
We correlated trinucleotide CAG repeat numbers in the huntingtin gene with the regional brain atrophy and clinical phenotype in 23 adult autopsy cases of Huntington's disease (HD). CAG repeat number (39-56, mean 45.4 +/- 4.6) correlated inversely (P < 0.0001) with age at onset and death, but not with disease duration or initial symptoms. Cross-sectional(More)
Cyanuric acid hydrolase (CAH) catalyzes the hydrolytic ring-opening of cyanuric acid (2,4,6-trihydroxy-1,3,5-triazine), an intermediate in s-triazine bacterial degradation and a by-product from disinfection with trichloroisocyanuric acid. In the present study, an X-ray crystal structure of the CAH-barbituric acid inhibitor complex from Azorhizobium(More)
We report a family in which Wolf-Hirschhorn syndrome in two children with partial monosomy of the short arm of chromosome 4 is the result of unbalanced segregation of a reciprocal 4;12 translocation in the mother. Studies with the DNA probe G8 show that the translocation breakpoint in this family is distal to the D4S10 locus. Previously reported cases of(More)
The known enzymes that open the s-triazine ring, the cyanuric acid hydrolases, have been confined almost exclusively to the kingdom Bacteria and are all homologous members of the rare cyanuric acid hydrolase/barbiturase protein family. In the present study, a filamentous fungus, Sarocladium sp. strain CA, was isolated from soil by enrichment culturing using(More)
Information on bacterial thioamide metabolism has focused on transformation of the antituberculosis drug ethionamide and related compounds by Mycobacterium tuberculosis. To study this metabolism more generally, a bacterium that grew using thioacetamide as the sole nitrogen source was isolated via enrichment culture. The bacterium was identified as Ralstonia(More)
The CAG repeat number on Huntington's disease (HD) chromosomes accounts for about 60% of the variance in the age at onset of HD. However, distinct familial factors may also influence the age at onset. HD is associated with loss of medium-sized GABA-ergic striatal output neurons. Intracerebral administration of human ciliary neurotrophic factor (CNTF)(More)
A uracil-to-cytosine mutation at nucleotide position 472 of oral poliovirus vaccine type 3 (OPV3) contributes to the development of vaccine-associated paralytic poliomyelitis (VAPP). To analyze OPV3 shedding patterns, we previously used the multistep method of mutant analysis by PCR and enzyme cleavage (MAPREC). This involves conventional reverse(More)
