  • Heredity was the main etiology, and consanguinity was high.[ncbi.nlm.nih.gov]
  • Because of extreme genetic heterogeneity, the etiology and genotypic spectrum of IRD have not been clearly defined, and there is limited information on genotype-phenotype correlations.[ncbi.nlm.nih.gov]
  • In this study, we wanted to clinically characterize and investigate the molecular etiology of an atypical form of autosomal recessive retinal dystrophy in two consanguineous Spanish families.[ncbi.nlm.nih.gov]
  • Results obtained in these families necessitated further genetic and clinical testing of additional family members to determine the complex genetic and phenotypic etiology of each family.[ncbi.nlm.nih.gov]
  • Etiology SECORD is genetically heterogeneous, being caused by many genes including those causing LCA ( ABCA4 (1p22), ADAMTS18 (16q23), AIPL1 (17p13.1), BEST1 (11q12), CRB1 (1q31.3), CRX (19q13.3), GUCY2D (17p13.1), IMPDH1 (7q31.3-q32), IMPG1 (6q14.2-q15[orpha.net]


  • Many of the dystrophies are the subject of clinical intervention trials, and nation-wide epidemiological data can help assess the future need for treatment.[ncbi.nlm.nih.gov]
  • Summary Epidemiology The prevalence is hard to predict as many SECORD patients have been previously diagnosed as Leber congenital amaurosis (LCA) patients.[orpha.net]
  • Summary Epidemiology The prevalence of AOFVD is unknown. Clinical description The clinical onset is typically between the fourth and sixth decade of life.[orpha.net]
  • Epidemiology Frequency United States Macular corneal dystrophy is uncommon, but areas with the highest prevalence include parts of the United States.[emedicine.medscape.com]
