Germ-line mutations in nonsyndromic pheochromocytoma.
Almost one fourth of patients with apparently sporadic pheochromocytoma may be carriers of mutations; routine analysis for mutations of RET, VHL, SDHD, and SDHB is indicated to identify pheosene-associated syndromes that would otherwise be missed.
PKHD1, the polycystic kidney and hepatic disease 1 gene, encodes a novel large protein containing multiple immunoglobulin-like plexin-transcription-factor domains and parallel beta-helix 1 repeats.
Autosomal recessive polycystic kidney disease (ARPKD) is a severe form of polycystic kidney disease that presents primarily in infancy and childhood and that is characterized by enlarged kidneys and
Mutation of the SBF2 gene, encoding a novel member of the myotubularin family, in Charcot-Marie-Tooth neuropathy type 4B2/11p15.
A large, novel gene, named SET binding factor 2 (SBF2), that lies within this interval and is expressed in various tissues, including spinal cord and peripheral nerve is identified and resemblance of the histopathological phenotype to that related to mutations in its paralogue MTMR2 indicate that this gene is the CMT4B2 gene.
Natural history in proximal spinal muscular atrophy. Clinical analysis of 445 patients and suggestions for a modification of existing classifications.
The definition of long-term characteristics of SMA is helpful in providing medical care to families with members who have SMA and also in providing important information for future genotype-phenotype studies and therapeutic trials of patients with SMA.
Mutations in the gene encoding immunoglobulin μ-binding protein 2 cause spinal muscular atrophy with respiratory distress type 1
It is demonstrated that SMARD type 1 (SMARD1) results from mutations in the gene encoding immunoglobulin μ-binding protein 2 (IGHMBP2), the second gene found to be defective in spinal muscular atrophy, and indicates that IGH MBP2 and SMN share common functions important for motor neuron maintenance and integrity in mammals.
Quantitative analysis of survival motor neuron copies: identification of subtle SMN1 mutations in patients with spinal muscular atrophy, genotype-phenotype correlation, and implications for genetic
Molecular genetic data for 42 independent nondeleted SMA patients is presented and the existence of further gene(s) responsible for approximately 4%-5% of phenotypes indistinguishable from SMA is suggested.
Mutations in the RNA exosome component gene EXOSC3 cause pontocerebellar hypoplasia and spinal motor neuron degeneration
These findings represent the first example of an RNA exosome core component gene that is responsible for a human disease and further implicate dysregulation of RNA processing in cerebellar and spinal motor neuron maldevelopment and degeneration.
Estimation of the Mutation Frequencies in Charcot-Marie-Tooth Disease Type 1 and Hereditary Neuropathy with Liability to Pressure Palsies: A European Collaborative Study
In the nonduplicated CMT1 patients, several different mutations were identified in the myelin genes PMP22, MPZ and Cx32, and several different mutated myelin proteins located on chromosomes 17p11.2, 1q21-q23 and Xq13.1 were identified.
Mutations in SIL1 cause Marinesco-Sjögren syndrome, a cerebellar ataxia with cataract and myopathy
Identification of SIL1 mutations implicates Marinesco-Sjögren syndrome as a disease of endoplasmic reticulum dysfunction and suggests a role for this organelle in multisystem disorders.
Clinical consequences of PKHD1 mutations in 164 patients with autosomal-recessive polycystic kidney disease (ARPKD).
This is the first study that reports the long-term outcome of ARPKD patients with defined PK HD1 mutations, indicating that PKHD1 mutation screening is a powerful diagnostic tool in patients suspected with AR PKD.
