Histidine Supplementation Stabilizes Hearing and Vision and Improves Growth in HARS1‐Related Autosomal Recessive Disorder Associated With Usher‐Like Symptoms

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal recessive HARS1‐related disorder (originally described as Usher syndrome type 3B) caused by a homozygous Y454S variant in the histidyl‐tRNA synthetase gene (HARS1) is characterized by progressive sensorineural hearing and vision loss and respiratory deterioration with risk for sudden death following febrile illnesses.

Longitudinal Structure–Function Evaluation in a Patient with CDHR1-Associated Retinal Dystrophy: Progressive Visual Function Loss with Retinal Remodeling

Diagnostics, 2023
Background: Retinal dystrophies related to damaging variants in the cadherin-related family member 1 (CDHR1) gene are rare and phenotypically heterogeneous.

Mutations in the Cone-Rod Homeobox Gene Are Associated with the Cone-Rod Dystrophy Photoreceptor Degeneration [PDF]

Neuron, 1997
Crx is a novel paired-like homeodomain protein that is expressed predominantly in retinal photoreceptors and pinealocytes. Its gene has been mapped to chromosome 19q13.3, the site of a disease locus for autosomal dominant cone-rod dystrophy (CORDII). Analysis of the proband from a family with autosomal dominant CORD revealed an Arg41Trp substitution in

Clinical manifestations of dual‐gene variants in retinitis pigmentosa

Acta Ophthalmologica, EarlyView.
Abstract Purpose Retinitis pigmentosa (RP) is an inherited retinal disease (IRD), whereby each affected individual typically harbours pathogenic variants in a single causative gene, yet the disorder exhibits marked genetic heterogeneity, with more than 100 genes reported to underlie RP.

Retinal dystrophies simulating geographic atrophy: A diagnostic challenge

Acta Ophthalmologica, EarlyView.
Abstract Geographic atrophy (GA) is the chronic loss of retinal pigment epithelium, photoreceptors and choriocapillaris, marking the dry late stage of age‐related macular degeneration (AMD). GA prevalence is expected to rise in the upcoming decades. Advanced GA leads to central scotomas, reducing visual acuity and quality of life, potentially resulting

Usher syndrome‐related visual impairment in Finland: A 35‐year nationwide register‐based study (1985–2019)

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate visual impairment (VI) associated with Usher syndrome (USH), a syndromic form of retinitis pigmentosa. Methods This register‐based study used data from the Register of the Finnish Federation for Visual Impairment for persons registered with USH‐related VI from 1985 to 2019.

CRB1‐Associated Inherited Retinal Dystrophies: Prospective Natural History Study With 4 Years of Follow‐Up

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background The lack of validated and sensitive clinical endpoints remains a major challenge in the design of gene therapy trials for inherited retinal dystrophies (IRDs). This prospective longitudinal cohort study describes the natural disease progression of IRDs caused by pathogenic mutations in the Crumbs homologue 1 (CRB1) gene, and ...

Choroidal Thickness in Different Types of Inherited Retinal Dystrophies

Journal of Ophthalmic & Vision Research, 2020
Purpose: To compare the choroidal thickness among eyes with retinitis pigmentosa (RP), Stargardt disease, Usher syndrome, cone-rod dystrophy, and healthy eyes of sex- and age-matched individuals. Methods: In this comparative study, 503 eyes with RP
