Three autosomal recessive disorders are associated with mutations in the RECQL4 gene: Rothmund-Thomson syndrome (RTS), Baller-Gerold syndrome (BGS), and RAPADILINO syndrome. BGS is characterized by two major clinical abnormalities: craniosynostosis and preaxial limb anomalies but not cancer development. We performed RECQL4 mutation detection in a patient with BGS and several ...

Blau syndrome is a rare, autosomal-dominant, autoinflammatory disorder characterized by granulomatous arthritis, uveitis, and dermatitis. Genetics studies have shown that the disease is caused by single nonsynonymous substitutions in NOD-2, a member of the NOD-like receptor or NACHT-leucine-rich repeat (NLR) family of intracellular proteins. Several NLRs function in the innate ...

Germline mutations in LKB1 cause Peutz-Jeghers syndrome (PJS), an autosomal dominant disorder with a predisposition to gastrointestinal polyposis and cancer. Hyperactivation of mTOR-signaling has been associated with PJS. We previously reported that rapamycin treatment of Lkb1(+/-) mice after the onset of polyposis reduced the polyp burden. Here we evaluated the ...

Craniosynostosis represents a defection of the skull caused by early fusion of one or more cranial sutures. The shape alteration of the cranial vault varies, depending on the fused sutures, so that compensatory growth occurs in dimensions not restricted by sutures. Craniosynostosis can be divided into two main groups: syndromic ...

Several congenital syndromes caused by germline mutations in tumor suppressor genes predispose to the development of glial tumors. In the last few decades our knowledge about the molecular functions of these genes and the pathogenesis of hereditary tumor syndromes has greatly increased. The most common syndromes are the neurofibromatoses (type ...

Human geneticists have shown that some progeroid syndromes are caused by mutations that interfere with the conversion of farnesyl-prelamin A to mature lamin A. For example, Hutchinson-Gilford progeria syndrome is caused by LMNA mutations that lead to the accumulation of a farnesylated version of prelamin A. In this review, we ...

The hereditary autoinflammatory diseases arise from mutations of genes regulating the innate immune system. These rare disorders are well characterized, both clinically and in terms of their molecular pathogenesis. The recurrent attacks of febrile polyserositis of Familial Mediterranean Fever (FMF) are due to defective pyrin, a protein that down-regulates inflammation. ...

When normal development and growth of the calvarial sutures is disrupted, craniosynostosis (premature calvarial suture fusion) may result. Classical craniosynostosis syndromes are autosomal dominant traits and include Apert, Pfeiffer, Crouzon, Jackson-Weiss, and Saethre-Chotzen syndromes. In these conditions, there is premature fusion of skull bones leading to an abnormal head shape, ...

The pathological nature of Leigh syndrome is highly variable and depends on the underlying mitochondrial or nuclear genome defect. Mitochondrial m.8993T>G and m.8993T>C mutations are responsible for both NARP (neurogenic weakness, ataxia and retinitis pigmentosa) and Leigh syndrome depending on the amount of mutant mtDNA. The clinical findings of Leigh ...
