Genetic insights into fetal kidney development: Variants in HNF1A and PKHD1 genes.

The orchestration of fetal kidney development involves the precise control of numerous genes, including HNF1A, HNF1B and PKHD1. Understanding the genetic factors influencing fetal kidney development is essential for unraveling the complexities of renal disorders. This study aimed to search for disease-causing variants in HNF1A, HNF1B, PKHD1 genes, among fetus and babies or via parental samples, using sanger sequencing, NGS technologie and MLPA.

Multiexon skipping leading to an artificial DMD protein lacking amino acids from exons 45 through 55 could rescue up to 63% of patients with Duchenne muscular dystrophy.

Approximately two-thirds of Duchenne muscular dystrophy (DMD) patients show intragenic deletions ranging from one to several exons of the DMD gene and leading to a premature stop codon. Other deletions that maintain the translational reading frame of the gene result in the milder Becker muscular dystrophy (BMD) form of the disease. Thus the opportunity to transform a DMD phenotype into a BMD phenotype appeared as a new treatment strategy with the development of antisense oligonucleotides technology, which is able to induce an exon skipping at the pre-mRNA level in order to restore an open reading frame.

[Cystic fibrosis in adults].

Objectives: At least half cystic fibrosis patients now reach adulthood.

Methods: We report a population of 61 patients above 18 years of age with the clinical pictures at time of diagnosis and the present clinical status.

Results: Thirty-five males and 26 females are aged from 18 to 47 years.

Diagnostic criteria for cystic fibrosis in men with congenital absence of the vas deferens.

The high frequency of cystic fibrosis (CF) mutations in males with absence of vas deferens supported the hypothesis of a primarily genital phenotype of CF disease. To consider the idea of an attenuated form of CF, we investigated 14 men with congenital bilateral aplasia of the vasa deferentia. All patients were consulting for infertility and none was known to have CF.
