Retinitis pigmentosa (RP) is the most frequent form of inherited retinopathy. RP is genetically heterogeneous with autosomal dominant, autosomal recessive and X-linked forms. Autosomal dominant retinitis pigmentosa (adRP) accounts for about 20-25% of all RP cases. At least ten adRP loci have so far been mapped. However, mutations causing adRP have been(More)
Mutations in the c-KIT gene have been identified in many sporadic and familial cases of gastrointestinal stromal tumor (GIST). We report a familial case of GIST with cutaneous hyperpigmentation associated with a novel germline mutation in the c-KIT gene. Screening for mutations in exon 11 of the c-KIT gene in genomic DNA from tumors and peripheral blood of(More)
PURPOSE Mutations in the systemically expressed pre-mRNA splicing-factor genes PRPF3, PRPF8, and PRPF31 have recently been associated with autosomal dominant retinitis pigmentosa (adRP). This study was intended to identify mutations in PRPF3, PRPF8, and PRPF31 in 150 Spanish families affected by adRP, to measure the contribution of mutations in these genes(More)
OBJECTIVE Genetic characterization of a series of patients with autosomal dominant retinitis pigmentosa (ADRP). METHODS All patients underwent complete ophthalmological examination including computerized perimetry, electroretinography and occasionally fluorescein angiography. Blood samples were drawn for genetic analysis of candidate genes namely(More)
Peutz-Jeghers syndrome (PJS) is an autosomal dominant disease, characterized phenotypically by mucocutaneous pigmentation and hamartomatous polyposis. Affected patients are at an increased risk of developing gastrointestinal and other malignancies. Mutations in the STK11/LKB1 (LKB1) gene, which encodes for a serine-threonine kinase, have been identified as(More)
Retinitis pigmentosa (RP), a clinically and genetically heterogeneous group of retinal degeneration disorders affecting the photoreceptor cells, is one of the leading causes of genetic blindness. Mutations in the photoreceptor-specific gene RP1 account for 3–10% of cases of autosomal dominant RP (adRP). Most of these mutations are clustered in a 500 bp(More)
PURPOSE To describe the genetic and clinical findings in a large Spanish pedigree with nail-patella syndrome (NPS) and to investigate the expressivity of open angle glaucoma (OAG) in the family members. METHODS All individuals underwent a complete ophthalmologic examination, including optical coherence tomography (OCT) of the optic disc and peripapillary(More)
