PURPOSE To investigate retinal function in patients with maternally inherited diabetes and deafness (MIDD) and to correlate the findings with fundus autofluorescence (FAF) imaging. METHODS FAF was imaged in five patients (age range, 49-60 years) confirmed to have the mitochondrial DNA nucleotide A3243G point mutation. Retinal function was measured by(More)
PURPOSE To test the incidence of mutations in RPGR ORF15 in six families with X-linked progressive retinal degeneration (cone-rod dystrophy [XLCORD], macular or cone dystrophy) and to undertake a detailed phenotypic assessment of families in whom ORF15 mutations were identified. METHODS To amplify and sequence ORF15 in its entirety, a cloning strategy was(More)
PURPOSE Retinitis pigmentosa is a clinically and genetically heterogeneous disorder. It is characterized by progressive degeneration of the peripheral retina, leading to night blindness and loss of the peripheral visual field. PRPF31 is one of four pre-mRNA splicing factors identified as causing autosomal dominant retinitis pigmentosa, with incomplete(More)
BACKGROUND Clinical interpretation of the large number of rare variants identified by high throughput sequencing (HTS) technologies is challenging. The aim of this study was to explore the clinical implications of a HTS strategy for patients with hypertrophic cardiomyopathy (HCM) using a targeted HTS methodology and workflow developed for patients with a(More)
OBJECTIVE A predictable relation between genotype and disease expression is needed in order to use genetic testing for clinical decision-making in hypertrophic cardiomyopathy (HCM). The primary aims of this study were to examine the phenotypes associated with sarcomere protein (SP) gene mutations and test the hypothesis that variation in non-sarcomere genes(More)
BACKGROUND Sarcomeric gene mutations cause hypertrophic cardiomyopathy (HCM). In gene mutation carriers without left ventricular (LV) hypertrophy (G + LVH-), subclinical imaging biomarkers are recognized as predictors of overt HCM, consisting of anterior mitral valve leaflet elongation, myocardial crypts, hyperdynamic LV ejection fraction, and abnormal(More)
PURPOSE Pseudoxanthoma elasticum (PXE; [MIM 264800]) is an autosomal recessive systemic disorder characterized by progressive degeneration and calcification of elastic fibers in connective tissue. The phenotype is variable, with cutaneous, vascular, and ophthalmic abnormalities. The disorder is a consequence of mutations in the ABCC6 gene. Visual impairment(More)
PURPOSE To determine (1) clinical features that distinguish maculopathy due to the R345W substitution in fibulin-3 from other forms of inherited or early-onset drusen, (2) the phenotypic variability, and (3) the extent of retinal disease in those with a positive molecular diagnosis. METHODS Affected individuals underwent ophthalmic examination, digital(More)
