A New Ocular Phenotype Combining Juvenile Glaucoma and Doyne Honeycomb Retinal Dystrophy (Malattia Leventinese) due to a Novel EFEMP1 Pathogenic Variant
Doyne honeycomb retinal dystrophy (DHRD), also termed malattia leventinese (MLVT), is a dominantly inherited ocular disease characterized by the progressive accumulation of macular and peripapillary drusenoid material beneath the retinal pigment epithelium in the Bruch membrane. In all affected individuals genetically characterized to date, DHRD/MLVT is caused by a single heterozygous p.Arg345Trp missense variant in the EGF‐containing fibulin‐like extracellular matrix protein 1, EFEMP1. Recently, pathogenic variants in the EFEMP1 gene have also been demonstrated in several families with juvenile or adult‐onset hereditary isolated glaucoma. Here, we describe a family featuring a unique phenotype of juvenile glaucoma and DHRD/MLVT caused by a novel EFEMP1 variant. Our results expand both the ocular phenotype associated with EFEMP1 variants and the molecular spectrum causing DHRD by describing the first non‐p.Arg345Trp EFEMP1 pathogenic allele.
期刊介绍:
The American Journal of Medical Genetics - Part A (AJMG) gives you continuous coverage of all biological and medical aspects of genetic disorders and birth defects, as well as in-depth documentation of phenotype analysis within the current context of genotype/phenotype correlations. In addition to Part A , AJMG also publishes two other parts:
Part B: Neuropsychiatric Genetics , covering experimental and clinical investigations of the genetic mechanisms underlying neurologic and psychiatric disorders.
Part C: Seminars in Medical Genetics , guest-edited collections of thematic reviews of topical interest to the readership of AJMG .
