Autosomal Recessive Primary Microcephaly (MCPH) is a rare disorder of neurogenic mitosis characterized by reduced head circumference at birth with variable degree of mental retardation. In MCPH patients, brain size reduced to almost one-third of its original volume due to reduced number of generated cerebral cortical neurons during embryonic neurogensis. So far, seven genetic loci (MCPH1-7) for...
BACKGROUND Primary autosomal recessive microcephaly (MCPH) is a rare neurodevelopmental disorder that results in severe microcephaly at birth with pronounced reduction in brain volume, particularly of the neocortex, simplified cortical gyration and intellectual disability. Homozygous mutations in the Cyclin-dependent kinase 5 regulatory subunit-associated protein 2 gene CDK5RAP2 are the cause o...
Microtubule nucleation and organization by the centrosome require gamma-tubulin, a protein that exists in a macromolecular complex called the gamma-tubulin ring complex (gammaTuRC). We report characterization of CDK5RAP2, a novel centrosomal protein whose mutations have been linked to autosomal recessive primary microcephaly. In somatic cells, CDK5RAP2 localizes throughout the pericentriolar ma...
cockayne syndrom: reporting a cases from iran confirmed by dna-repair and direct sequencing analysis
cockayne syndrome is a very rare genetic disorder with a recessive autosomal mode of inheritance characterized by dwarfism, microcephaly, mental retardation, deafness, photosensive dermatitis and a peculiar form of retinal pigmentation. we report an iranian family with one affected child who suffers from cockayne syndrome. cardinal features are failure to thrive, short stature, premature aging,...
Caprine-like Generalized Hypoplasia Syndrome (SHGC) is an autosomal-recessive disorder in Montbéliarde cattle. Affected animals present a wide range of clinical features that include the following: delayed development with low birth weight, hind limb muscular hypoplasia, caprine-like thin head and partial coat depigmentation. Here we show that SHGC is caused by a truncating mutation in the CEP2...
Purpose: To identify the causative gene for phenotypes associating autosomal recessive congenital cataract, mental retardation and congenital cataract, mental retardation and microcephaly in four unrelated Tunisian families. Methods: Four genes (EPHA2, GALK1, GCNT2, and CRYBB1) were selected based on their expression in human brain and their known or putative function. Linkage analysis were per...
BACKGROUND Isolated sulfite oxidase deficiency (ISOD), caused by mutations in SUOX gene, is an autosomal recessive disease manifesting with early onset seizures, developmental delay, microcephaly, and spasticity. It mimics hypoxic-ischemic encephalopathy (HIE) the neonatal period characterized progressive severe neurological impairment due to accumulation of toxic metabolites. CASE This report ...
