Frequency of 657del(5) mutation of the NBS1 gene in the Czech population by polymerase chain reaction with sequence specific primers
2002
Abstract Nijmegen breakage syndrome is an autosomal recessive chromosomal instability syndrome characterized by microcephaly, immunodeficiency, radiosensitivity, and predisposition to lymphoid malignancy. A truncating deletion [657del(5)] in exon 6 of the nibrin NBS1 gene is the most frequent cause of the syndrome. Slavic populations carry this mutation in a high frequency. Here, we present polymerase chain reaction with sequence specific primers as a method for the detection of Slavic NBS1 mutation and confirm the high carrier frequency in the Czech population (combined frequency from both studies: 1/106, 95% CI=1/331 to 1/46).
