as a result of higher distributed consanguinity in the mediterranean region and the middle east, autosomal-recessive forms of charcot-marie-tooth (arcmt) are more common in these areas. cmt disease caused by mutations in the ganglioside-induced differentiation-associated protein 1 (gdap1) gene is a severe autosomal recessive neuropathy resulting in either demyelinating cmt4a neuropathy or axona...

farber lipogranulomatosis is a rare inherited condition involving the breakdown and use of fats in the body (lipid metabolism). characteristics are early-onset subcutaneous nodules, painful and progressively deformed joints, and hoarseness by laryngeal involvement in affected individuals, lipids accumulate abnormally in cells and tissues throughout the body, particularly around the joints. thre...

chronic granulomatous disease (cgd) is a rare primary immunodeficiency disorder due to a genetic defect in one of the components of nicotinamide adenine dinucleotide phosphate (nadph) oxidase complex. this complex is composed of membrane-bound gp91- phox and p22- phox subunits, and cytosolic subunits consisting of p47- phox , p67- phox , and p40- phox . a mutation in cybb gene encoding gp91- ph...

Background: Cystic fibrosis (CF) is a common autosomal recessive disorder that affects many body systems and is produced by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. CF is also the most frequently inherited disorder in the West. The aim of this study was to detect the mutations in the CFTR gene in two Iranian families with CF. Methods: After DNA extractio...

congenital generalized lipodystrophies (cgls) are very rare autosomal recessive disorders which have four types.of the four cgl types, bscl2 (berardinelli–seip congenital lipodystrophy type 2) is the result of mutations in the bscl2/seipingene.bscl2 which is the most severe lipodystrophic phenotype is characterized by generalized lipodystrophy, overgrowth,acanthosisnigricans, hepatomegaly, insu...

Background and Aims: One of the most important genes involved in Alzheimer's disease (AD) is the presenilin2 (PSEN2) gene, which is one of the main constituents of the gamma-secretase complex. Mutations in this gene promote the formation of amyloid plaques resulting in AD. The study aimed to evaluate the mutation variant in exon 6 of the PSEN2 gene in patients with Late-Onset AD (LOAD). Due to ...
