PURPOSE To evaluate genotypic and macular morphologic correlations in patients with RPE65-, CEP290-, GUCY2D-, or AIPL1-related Leber congenital amaurosis (LCA) using spectral-domain optical coherence tomography (SD-OCT). METHODS SD-OCT macular scans were performed in 21 patients, including 10 with RPE65, 7 with CEP290, 3 with GUCY2D, and 1 with AIPL1 mutations. An image processing software wa...
PURPOSE To localize and identify the gene and mutations causing autosomal recessive retinal dystrophy in two consanguineous Pakistani families. METHODS Consanguineous families from Pakistan were ascertained to be affected with autosomal recessive retinal degeneration. All affected individuals underwent thorough ophthalmologic examinations. Blood samples were collected, and genomic DNA was ext...
نابینایی مادرزادی لبر شدیدترین بیماری تحلیل ارثی شبکیه در انسان است. این بیماری به لحاظ ژنتیکی ناهمگن بوده و معمولاً به صورت آتوزومی مغلوب به ارث می رسد. مشخص شده است که انواع جهش ها در ژن aipl1 منجر به ایجاد شدیدترین شکل های این بیماری می شوند. اصولا" تعیین توالی به منظور شناسایی جهش های نقطه ای و دیگر تنوعات توالی موجود در این ژن استفاده می شود که بسیار وقت گیر و پر هزینه میباشد. از این رو روش...
PURPOSE To describe the clinical and genetic findings in a Chinese family with autosomal dominant cone dystrophy (adCOD). METHODS One family was examined clinically, and genomic DNA was extracted from venous blood of all participants. Genotyping and haplotyping analysis was performed on the known genetic loci for adCOD and autosomal dominant cone-rod dystrophies (adCORD) with a panel of polym...
PURPOSE Leber congenital amaurosis (LCA) and early-onset severe retinal dystrophy (EOSRD) are genetically heterogeneous, with 11 genes currently implicated. The LCA chip may be used to interrogate many variants in one hybridization reaction. The purpose of this study was to assess the utility of this technology. METHODS One hundred fifty-three patients with LCA and EOSRD were screened using a...
PURPOSE Paclitaxel is used worldwide in the treatment of breast, lung, ovarian, and other cancers. Sensory peripheral neuropathy is an associated adverse effect that cannot be predicted, prevented, or mitigated. To better understand the contribution of germline genetic variation to paclitaxel-induced peripheral neuropathy, we undertook an integrative approach that combines genome-wide associati...
PURPOSE To test the efficiency of a microarray chip as a diagnostic tool in a cohort of northwestern European patients with Leber congenital amaurosis (LCA) and to perform a genotype-phenotype analysis in patients in whom pathologic mutations were identified. METHODS DNAs from 58 patients with LCA were analyzed using a microarray chip containing previously identified disease-associated sequen...
OBJECTIVES To report the genetic basis of Leber congenital amaurosis (LCA) in northern Pakistan and to describe the phenotype. METHODS DNA from 14 families was analyzed using single-nucleotide polymorphism and microsatellite genotyping and direct sequencing to determine the genes and mutations involved. The history and examination findings from 64 affected individuals were analyzed to show ge...
ZP3 is a principal component of the zona pellucida (ZP) of mammalian oocytes and is essential for normal fertility, and knockout of ZP3 causes complete infertility. ZP3 promotes fertilization by recognizing sperm binding and activating the acrosome reaction; however, additional cellular roles for ZP3 in mammalian oocytes have not been yet reported. In the current study, we found that ZP3 was st...
