Analysis of rearrangements of the CFTR gene in patients from Turkey with CFTR-related disorders: frequent exon 2 deletion.

Cystic fibrosis is a hereditary disease that mostly affects the sweat glands, respiratory system, digestive system, and reproductive system. Many and various types of mutations have been reported in CFTR in different ethnicities and countries/regions. Analysis of CFTR gene rearrangements is recommended in patients with unidentified mutated alleles in CFTR sequencing analysis. We collected MLPA analyses of 527 patients from Turkey who had at least one unidentified mutation in CFTR sequence analysis. Heterozygous/homozygous deletions were detected in the CFTR gene in 49 individuals (9.2%) from 35 families. Twelve different single/multi exon deletions were demonstrated, two of which were not previously reported in the literature. Mutations have previously reported in patients from various regions including Asia, Europe, and Africa, and Turkey is located at a crossroads between them. The most frequent mutation was the exon 2 deletion, accounting for 60%. Moreover, patients with exon 2 deletions, were especially originated from northern Turkey. This finding is valuable in leading and shaping planned screening programs in Turkey. Our study, the most comprehensive study for rearrangement analysis in patients from Tukey, revealed a candidate hotspot region of patients suspected of having CFTR-related disorders from Turkey.

[Urogenital bilharziasis: imaging diagnosis]. / Bilharziose urogénitale: diagnostic par imagerie.

Urogenital bilharziasis is a well-known disease that seldom is encountered in western countries. Therefore, bilharziasis usually only is considered after tuberculosis, the main differential diagnosis, has been excluded. Using this case, we will discuss the value of different imaging techniques (especially that of CT combined with transrectal US) for diagnosing bilharziasis and review specific criteria to more easily distinguish both pathologies.
