CC2D2Amutations in Meckel and Joubert syndromes indicate a genotype-phenotype correlation

Clinical and genetic heterogeneity of the Joubert and Meckel syndromes

Introduction Identification of genes causing inherited cystic kidney diseases has triggered a major interest for the concept of ‘ciliopathies’. Indeed, almost all of the proteins involved in human renal cystic diseases are expressed in the primary cilium complex located in renal epithelial cells. Primary cilia are cellular extensions containing a microtubulebased axoneme covered by a specialize...

Unraveling the genetics of Joubert and Meckel-Gruber syndromes.

Joubert (JBTS) and Meckel-Gruber (MKS) syndromes are recessive neurodevelopmental conditions caused by mutations in proteins that are structural or functional components of the primary cilium. In this review we provide an overview of their clinical diagnosis, management and molecular genetics. Both have variable phenotypes, extreme genetic heterogeneity, and display allelism both with each othe...

Chromosome Duplication (14q) and The Genotype Phenotype Correlation

Genotype-phenotype correlation in CC2D2A-related Joubert syndrome reveals an association with ventriculomegaly and seizures.

BACKGROUND Joubert syndrome (JS) is a ciliopathy characterised by a distinctive brain malformation (the 'molar tooth sign'), developmental delay, abnormal eye movements and abnormal breathing pattern. Retinal dystrophy, cystic kidney disease, liver fibrosis and polydactyly are variably present, resulting in significant phenotypic heterogeneity and overlap with other ciliopathies. JS is also gen...

FMF Genotype-phenotype correlation in Iranian Azeri Turks: Association between M694V/R761H mutation and amyloidosis

Objective(s):Familial Mediterranean fever (FMF), an inherited autosomal recessive disorder, is frequently present among individuals of Mediterranean origin. Differences in the clinical manifestations of FMF between different ethnic groups have been documented. The aim of the present study was to determine the most common characteristics of FMF and the relationship between clinical findings and ...
