Sentence |
denotes |
Nijmegen breakage syndrome in 13% of age-matched Czech children with primary microcephaly. |
| T2 |
91-354 |
Sentence |
denotes |
The Nijmegen breakage syndrome is a rare autosomal recessive chromosomal instability disorder characterized by early growth retardation, congenital microcephaly, immunodeficiency, borderline mental development, and a high tendency to lymphoreticular malignancies. |
| T3 |
355-515 |
Sentence |
denotes |
Most Nijmegen breakage syndrome patients are of Slavonic origin, and all of them known so far carry a founder homozygous 5 nucleotide deletion in the NBS1 gene. |
| T4 |
516-638 |
Sentence |
denotes |
Microcephaly was present in 100% of Nijmegen breakage syndrome patients in a recent large international cooperative study. |
| T5 |
639-738 |
Sentence |
denotes |
The frequency of Nijmegen breakage syndrome among children with primary microcephaly was not known. |
| T6 |
739-834 |
Sentence |
denotes |
Early correct diagnosis of the syndrome is crucial for appropriate preventive care and therapy. |
| T7 |
835-968 |
Sentence |
denotes |
We tested 67 Czech patients of different ages with simple microcephaly for the presence of the most common mutation in the NBS1 gene. |
| T8 |
969-1074 |
Sentence |
denotes |
Three new Nijmegen breakage syndrome cases were detected in this cohort, representing 4.5% of the cohort. |
| T9 |
1075-1190 |
Sentence |
denotes |
All these newly diagnosed Nijmegen breakage syndrome patients were younger than 10 months at the time of diagnosis. |
| T10 |
1191-1235 |
Sentence |
denotes |
They were all born within a 2.5-year period. |
| T11 |
1236-1380 |
Sentence |
denotes |
Twenty-three of the 67 children in the cohort were born within this 2.5-year period, representing a 13% incidence of Nijmegen breakage syndrome. |
| T12 |
1381-1476 |
Sentence |
denotes |
Frequency of Nijmegen breakage syndrome heterozygotes among infants in the Czech Republic is 1: |
| T13 |
1477-1638 |
Sentence |
denotes |
130-158 and the birth rate is 90,000 per year, therefore in the time span of 2.5 years, three new Nijmegen breakage syndrome homozygotes are expected to be born. |
| T14 |
1639-1799 |
Sentence |
denotes |
Therefore we assume that by DNA testing of Czech primary microcephalic children it is possible to detect all Nijmegen breakage syndrome patients to be expected. |
| T15 |
1800-1916 |
Sentence |
denotes |
The age at correct diagnosis was lowered from 7.1 years at the time before DNA testing, to well under 1 year of age. |
| T16 |
1917-2075 |
Sentence |
denotes |
All new Nijmegen breakage syndrome patients could receive appropriate preventive care, which should significantly improve their life expectancy and prognosis. |
