Objectives. There have been advances in the identification and understanding of molecular subsets of lung cancer, defined by specific oncogenic aberrations. A number of actionable genetic alterations have been identified, such as the epidermal growth factor receptor (EGFR) mutation. We aimed to establish the reasons why patients were not undergoing EGFR mutation testing at the time of histologi...

BACKGROUND Congenital nephrotic syndrome of Finnish type (NPHS1) is an autosomal recessive disorder characterized by severe proteinuria of intrauterine onset. Ninety-four percent of the Finnish NPHS1 chromosomes have been reported to carry either a 2-bp deletion in exon 2 (Fin(Major)) or a nonsense mutation in exon 26 (Fin(Minor)) of the NPHS1 gene. The high prevalence of only two mutations in ...

Here we elucidated the pathogenesis of a 14-year-old Chinese female who initially developed an isolated nephropathy followed by a complex clinical presentation with brain and muscle problems, which indicated that the disease process was possibly due to a mitochondrial dysfunction. Careful evaluation of renal biopsy samples revealed a decreased staining of cells induced by COX and NADH dehydroge...

BACKGROUND Osteogenesis Imperfecta (OI) is a heritable connective tissue disorder mainly caused by mutations in the genes COL1A1 and COL1A2 and is associated with hearing loss in approximately half of the cases. The hearing impairment usually starts between the second and fourth decade of life as a conductive hearing loss, frequently evolving to mixed hearing loss thereafter. A minority of pati...

PURPOSE To investigate the association between genotype (methyl-CpG-binding protein 2 (MECP2 gene mutation)) and epileptic seizure phenotype in Rett syndrome. METHODS We used the British Isles Rett syndrome survey to identify 137 subjects with one of the nine most frequent MECP2 gene mutations and invited their parents or carers to participate in a postal questionnaire and telephone interview...

OBJECTIVE To evaluate the role of targeted prostate cancer screening in men with BRCA1 or BRCA2 mutations, an international study, IMPACT (Identification of Men with a genetic predisposition to ProstAte Cancer: Targeted screening in BRCA1/2 mutation carriers and controls), was established. This is the first multicentre screening study targeted at men with a known genetic predisposition to prost...

Heterozygous mutations in the human Kir6.2 gene (KCNJ11), the pore-forming subunit of the ATP-sensitive K(+) channel (K(ATP) channel), are a common cause of neonatal diabetes. We identified a novel KCNJ11 mutation, R50Q, that causes permanent neonatal diabetes (PNDM) without neurological problems. We investigated the functional effects this mutation and another at the same residue (R50P) that l...

Glucose-6-Phosphate Dehydrogenase (G6PD) is a cytosolic enzyme which its main function is to produce NADPH in the red blood cells by controlling the step from Glucose-6-Phosphate to 6-Phospho gluconate in the pentose phosphate pathway. G6PD deficiency is the most common X-chromosome linked hereditary enzymopathy in the world, that result in reduced enzyme activity and more than 125 different mu...
