Abstract

Background

Fanconi anemia (FA)-A is the most frequent complementation group and is detected in approximately two-thirds of studied FA patients in most countries.

Aim

The aim of the study was to screen for the common mutations previously reported in the international literature within exons 27, 34, 38, and 43 of the FANCA gene among Egyptian FA patients.

Patients and methods

The study included 24 Egyptian FA patients of unrelated consanguineous pedigrees and diagnosed by positive chromosomal breakage studies using diepoxybutane. Ten healthy unrelated individuals of matching age and sex were included as the control group. Genomic DNA amplification, sequencing of exons 27, 34, and 43 of the FANCA gene, and restriction enzyme analysis for the exon 38 3788–3790del mutation were performed for patients and controls.

Results

No mutations were detected within the studied FANCA gene exons.

Conclusion

Absence of mutations within the studied exons may denote a different FA molecular pattern in Egyptian patients. Further studies are recommended to define the underlying mutations among Egyptian FA cases as an important step in disease control.
