View original source ↗Export metadata ↓

Abstract

Monoclinic crystals of the sodium salt of cytidine 2',3'-phosphate contain two anions in the asymmetric unit. Both bases are in the syn conformation, and the nucleotides are stacked together into an antiparallel stranded ribbon with the bases 3.3 angstroms apart. One ribose ring is planar, and the other has oxygen-1' puckered toward carbon-5'. The phosphorus atoms in the five-membered ester rings are puckered toward the sugars. The conformations about the carbon-4'-carbon-5' bonds are gauche-trans and gauche-gauche.

CTG repeat polymorphism in DMPK gene in healthy Yugoslav population.

OBJECTIVES: Myotonic dystrophy type 1 (DM1) is caused by large expansions of cytosine-thymine-guanine (CTG)-repeats in myotonic dystrophy protein kinase (DMPK)-gene. This gene is highly polymorphic in healthy individuals. It has been proposed that expanded alleles originated from the group of large sized normal alleles. If this is correct, one should expect a positive correlation between the frequency of large sized normal alleles and a prevalence of this disorder in a population. In this paper we determined the distribution of alleles of DMPK gene in healthy Yugoslav population. MATERIAL AND METHODS: A sample of 235 healthy individuals of Yugoslav origin have been genotyped for the alleles of DMPK locus. RESULTS: We found 22 different alleles, ranging in size from 5 to 29 repeats. Among 470 chromosomes studied, 41 chromosomes had more than 18 repeats (8.72%). CONCLUSIONS: Relatively high frequency of large sized normal alleles found in our population, suggest that prevalence of DM1 in Yugoslavia should not be different from the prevalence in other European populations.

Direct DNA testing for fragile X syndrome.

The recent identification of an abnormally amplified trinucleotide (cytosine guanine guanine) repeat in the fragile X gene (FMR-1) of males with fragile X syndrome and their carrier mothers allows the study of the mutation in individuals at risk. In this report, data on 396 patients and 35 normal controls are reported. Included in this sample are patients with no known family history of fragile X syndrome or mental retardation for whom the risks of fragile X syndrome are unclear. All 39 cytogenetically positive affected males and six females had the full mutation, as represented by a restriction fragment size increase (delta) of 500 base pairs (bp) or more within the cytosine guanine guanine repeat-bearing fragment of the FMR-1 gene; and all 16 of the normal obligate carrier females bore the premutation, as demonstrated by a delta of 100 to 500 bp. Of 124 patients (62 males and 62 females) with a family history of fragile X syndrome, five (8%) of the males and 25 (40%) of the females had the premutation. Five (2.2%) of the 231 mentally impaired patients with no confirmed family history of fragile X syndrome were found to have the full mutation. Twelve (33%) of 36 mentally impaired males and one (20%) of five females with unknown family history were found to carry an amplified cytosine guanine guanine repeat. Using this technique, we also reevaluated risk assessments previously generated by linkage analysis and unambiguously determined the carrier status of individual family members.
