Primary cataracts are breed-related eye diseases and are common in many dog breeds. In this study, 17 genes (BFSP2, EYA1, FOXE3, FTL, GCNT2, GJA3, GJA8, HSF4, MAF, MIP, PAX6, PITX3, SIX5, SORD, SOX1, SPARC, TRNT1) were evaluated as candidates for primary non-congenital cataracts (CAT) in the Dachshund using microsatellites adjacent to the candidate genes. Linkage and association with CAT was tested in 15 affected and six unaffected wire-haired Dachshunds. Non-parametric linkage analysis and association tests did not reveal significant linkage or association for the candidate gene flanking microsatellites tested. Thus, it is unlikely that the 17 investigated candidate genes harbour a causative mutation for CAT in these Dachshunds.

Congenital cataract is the common cause of visual disability in children. Inherited isolated (non-syndromic) cataract represents one third of cases. Currently, at least 22 specific genes associated with isolated inherited cataract have been identified: ten crystallin genes: CRYAA, CRYAB, CRYBA1/A3, CRYBA4, CRYBB1, CRYBB2, CRYBB3, CRYGC, CRYGD, CRYGS; 4 membrane protein genes: GJA3, GJA8, MIP, LIM2; three growth and transcription factor genes: PITX3, MAF, HSF4; two cytoskeletal protein gene: BSFP1, BSFP2; chromatin modifying protein-4B gene: CHMP4B, EPHA2 and NHS, it is likely that more genes remain to be discovered. Some of the genes have been studied for their function by expression in cells or/and by knock-out animal models. The increasing availability of more detailed information about their functions makes it possible to understand the pathophysiology of congenital cataracts.

Congenital cataract is a crystallin severe blinding disease and genetic factors in disease development are important. Crystallin growth is under a combination of genes and their products in time and space to complete the coordination role of the guidance. Congenital cataract-related genes, included crystallin protein gene (CRYAA, CRYAB, CRYBA1/A3, CRYBA4, CRYBB1, CRYBB2, CRYBB3, CRYGC, CRYGD, CRYGS), gap junction channel protein gene (GJA1, GJA3, GJA8), membrane protein gene (GJA3, GJA8, MIP, LIM2), cytoskeletal protein gene (BF-SP2), transcription factor genes (HSF4, MAF, PITX3, PAX6), ferritin light chain gene (FTL), fibroblast growth factor (FGF) and so on. Currently, there are about 39 genetic loci isolated to which primary cataracts have been mapped, although the number is constantly increasing and depends to some extent on definition. We summarized the recent advances on epidemiology and genetic locations of congenital cataract in this review.

Congenital cataracts are a significant cause of lifelong visual loss. They may be isolated or associated with microcornea, microphthalmia, anterior segment dysgenesis (ASD) and glaucoma, and there can be syndromic associations. Genetic diagnosis is challenging due to marked genetic heterogeneity. In this study, next-generation sequencing (NGS) of 32 cataract-associated genes was undertaken in 46 apparently nonsyndromic congenital cataract probands, around half sporadic and half familial cases. We identified pathogenic variants in 70% of cases, and over 68% of these were novel. In almost two-thirds (20/33) of these cases, this resulted in new information about the diagnosis and/or inheritance pattern. This included identification of: new syndromic diagnoses due to NHS or BCOR mutations; complex ocular phenotypes due to PAX6 mutations; de novo autosomal-dominant or X-linked mutations in sporadic cases; and mutations in two separate cataract genes in one family. Variants were found in the crystallin and gap junction genes, including the first report of severe microphthalmia and sclerocornea associated with a novel GJA8 mutation. Mutations were also found in rarely reported genes including MAF, VIM, MIP, and BFSP1. Targeted NGS in presumed nonsyndromic congenital cataract patients provided significant diagnostic information in both familial and sporadic cases.
