UNLABELLED Cherubism is classified within the group of benign osteo-fibrous lesions. Aside from facial deformities, it may account for major complications. It has been observed that the disease is caused by a mutation in the gene SH3BP2 (SH3-domain binding protein 2), which is located at chromosome 4pl6.3. Here we present two cases of familial cherubism, uncle and nephew, with variable clinical...

Purpose: We studied the inheritance pattern, clinical features and outcome in children with vesicoureteral reflux (VUR). Characteristics of known familial VUR cases were also compared with those of sporadic VUR. Material and Methods: 726 patients were treated for VUR between 19902004. The families were contacted by letter inquiring if other members of the family were affected. The phenotype of ...

A crucial tenet of the prion hypothesis is that misfolding of the prion protein (PrP) induced by mutations associated with familial prion disease is, in an otherwise normal mammalian brain, sufficient to generate the infectious agent. Yet this has never been demonstrated. We engineered knockin mice to express a PrP mutation associated with a distinct human prion disease, fatal familial insomnia...

BACKGROUND Intravenous drug use, sexual promiscuity and a longer cohabitation period are considered risk factors for familial transmission of hepatitis C virus. The relative importance of this type of transmission is a subject of controversy. AIM To study familial clustering of hepatitis C virus infection and its risk factors. MATERIAL AND METHODS HCV positive patients (91 with chronic hepa...

In seven pedigrees displaying the familial atypical multiple mole-melanoma (FAMMM) syndrome, three successive linkage analyses were performed between HLA and an assumed dominant gene determining respectively each of the following affected phenotypes: (1) precursor lesions, (2) cutaneous malignant melanoma (CMM), and (3) precursor lesions or CMM or both. Close linkage could be excluded in (1) an...

Opiate reward memories are powerful triggers for compulsive opiate-seeking behaviors. The basolateral amygdala (BLA) is an important structure for the processing of opiate-related associative memories and is functionally linked to the mesolimbic dopamine (DA) pathway. Transmission through intra-BLA DA D1-like and D2-like receptors independently modulates the formation of opiate reward memories ...

Premature ovarian failure is defined as cessation of ovarian function under the age of 40 years and affects approximately 1% of women in the general population. The aetiology of this disorder is still unknown in most cases. Although there have been some reports of familial premature ovarian failure, very little is known about the incidence and inheritance pattern of its idiopathic form. The aim...
