The defective splicing of pre-mRNA is a major cause of human disease. Exon skipping is a common result of splice mutations and has been reported in a wide variety of genetic disorders, yet the underlying mechanism is poorly understood. Often, such mutations are incompletely penetrant, and low levels of normal transcript and protein are maintained. Familial(More)
Familial dysautonomia (FD) is the best-known and most common member of a group of congenital sensory/autonomic neuropathies characterized by widespread sensory and variable autonomic dysfunction. As opposed to the sensory/motor neuropathies, little is known about the causes of neuronal dysfunction and loss in the sensory/autonomic neuropathies. FD involves(More)
The specific chromosomal translocation t(X;1)(p11.2;q21.2) has been observed in human papillary renal cell carcinomas. In this study we demonstrated that this translocation results in the fusion of a novel gene designated PRCC at 1q21.2 to the TFE3 gene at Xp11.2. TFE3 encodes a member of the basic helix-loop-helix (bHLH) family of transcription factors(More)
In this study we have screened a series of 29 primary leiomyosarcomas for abnormalities of both the p53 gene and the MDM2 gene, which encodes a p53-associated protein. SSCP (single-strand conformation polymorphism) analysis and direct sequencing of polymerase chain reaction (PCR)-amplified DNA were used to establish that 6/29 tumours possessed point(More)
Purpose. Amplification of genetic sequences on chromosome 12q13 is frequently found in soft tissue tumours. However, for the MDM2 gene, over-expression of the MDM2 protein has not always been shown to accompany gene amplification, raising the possibility that amplification of genetic sequences targets alternative genes on chromosome 12q13 for(More)
We have used single-strand conformation polymorphism (SSCP) analysis to screen for mutations in the BCL10 gene in 81 primary prostate carcinomas, 20 squamous cell cancers of the head and neck, 15 small-cell lung cancer cell lines, 24 renal carcinoma cell lines and 13 sarcoma cell lines. We failed to find evidence of somatically acquired mutations of the(More)
Purpose/Method. Transfection experiments have been used to identify activated oncogenes in a wide variety of tumour types. Here we describe the use of transfection experiments utilizing DNA from a human pleomorphic liposarcoma to identify a novel gene, designated lip which maps to chromosome 19.Results. lip was expressed in all sarcoma cell lines examined(More)
