Whole Exome Sequencing Gene Package Vision Disorders, Version 6.1, 31-1-2020
Whole Exome Sequencing Gene package Vision disorders, version 6.1, 31-1-2020 Technical information DNA was enriched using Agilent SureSelect DNA + SureSelect OneSeq 300kb CNV Backbone + Human All Exon V7 capture and paired-end sequenced on the Illumina platform (outsourced). The aim is to obtain 10 Giga base pairs per exome with a mapped fraction of 0.99. The average coverage of the exome is ~50x. Duplicate and non-unique reads are excluded. Data are demultiplexed with bcl2fastq Conversion Software from Illumina. Reads are mapped to the genome using the BWA-MEM algorithm (reference: http://bio-bwa.sourceforge.net/). Variant detection is performed by the Genome Analysis Toolkit HaplotypeCaller (reference: http://www.broadinstitute.org/gatk/). The detected variants are filtered and annotated with Cartagenia software and classified with Alamut Visual. It is not excluded that pathogenic mutations are being missed using this technology. At this moment, there is not enough information about the sensitivity of this technique with respect to the detection of deletions and duplications of more than 5 nucleotides and of somatic mosaic mutations (all types of sequence changes).

Insight Into the Molecular Genetics of Myopia
Molecular Vision 2017; 23:1048-1080 <http://www.molvis.org/molvis/v23/1048> © 2017 Molecular Vision Received 8 May 2017 | Accepted 29 December 2017 | Published 31 December 2017 Insight into the molecular genetics of myopia Jiali Li, Qingjiong Zhang State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China Myopia is the most common cause of visual impairment worldwide. Genetic and environmental factors contribute to the development of myopia. Studies on the molecular genetics of myopia are well established and have impli- cated the important role of genetic factors. With linkage analysis, association studies, sequencing analysis, and experimental myopia studies, many of the loci and genes associated with myopia have been identified. Thus far, there has been no systemic review of the loci and genes related to non-syndromic and syndromic myopia based on the different approaches. Such a systemic review of the molecular genetics of myopia will provide clues to identify additional plausible genes for myopia and help us to understand the molecular mechanisms underlying myopia. This paper reviews recent genetic studies on myopia, summarizes all possible reported genes and loci related to myopia, and suggests implications for future studies on the molecular genetics of myopia. 1. Introduction: late-onset high myopia commonly seen in university students) Myopia is the most common cause of visual impairment or a Mendelian trait (such as most early-onset high myopia worldwide.

Ophthalmology
Ophthalmology Information for health professionals MEDICAL GENETIC TESTING FOR OPHTHALMOLOGY Recent technologies, in particularly Next Generation Sequencing (NGS), allows fast, accurate and valuable diagnostic tests. For Ophthalmology, CGC Genetics has an extensive list of medical genetic tests with clinical integration of results by our Medical Geneticists. 1. EXOME SEQUENCING: Exome Sequencing is a very efficient strategy to study most exons of a patient’s genome, unraveling mutations associated with specific disorders or phenotypes. With this diagnostic strategy, patients can be studied with a significantly reduced turnaround time and cost. CGC Genetics has available 2 options for Exome Sequencing: • Whole Exome Sequencing (WES), which analyzes the entire exome (about 20 000 genes); • Disease Exome by CGC Genetics, which analyzes about 6 000 clinically-relevant genes. Any of these can be performed in the index case or in a Trio. 2. NGS PANELS For NGS panels, several genes associated with the same phenotype are simultaneously sequenced. These panels provide increased diagnostic capability with a significantly reduced turnaround time and cost. CGC Genetics has several NGS panels for Ophthalmology that are constantly updated (www.cgcgenetics.com). Any gene studied in exome or NGS panel can also be individually sequenced and analyzed for deletion/duplication events. 3. EXPERTISE IN MEDICAL GENETICS CGC Genetics has Medical Geneticists specialized in genetic counseling for ophthalmological diseases who may advice in choosing the most appropriate -

Ocular Colobomaâ
Eye (2021) 35:2086–2109 https://doi.org/10.1038/s41433-021-01501-5 REVIEW ARTICLE Ocular coloboma—a comprehensive review for the clinician 1,2,3 4 5 5 6 1,2,3,7 Gopal Lingam ● Alok C. Sen ● Vijaya Lingam ● Muna Bhende ● Tapas Ranjan Padhi ● Su Xinyi Received: 7 November 2020 / Revised: 9 February 2021 / Accepted: 1 March 2021 / Published online: 21 March 2021 © The Author(s) 2021. This article is published with open access Abstract Typical ocular coloboma is caused by defective closure of the embryonal fissure. The occurrence of coloboma can be sporadic, hereditary (known or unknown gene defects) or associated with chromosomal abnormalities. Ocular colobomata are more often associated with systemic abnormalities when caused by chromosomal abnormalities. The ocular manifestations vary widely. At one extreme, the eye is hardly recognisable and non-functional—having been compressed by an orbital cyst, while at the other, one finds minimalistic involvement that hardly affects the structure and function of the eye. In the fundus, the variability involves the size of the coloboma (anteroposterior and transverse extent) and the involvement of the optic disc and fovea. The visual acuity is affected when coloboma involves disc and fovea, or is complicated by occurrence of retinal detachment, choroidal neovascular membrane, cataract, amblyopia due to uncorrected refractive errors, etc. While the basic birth anomaly cannot be corrected, most of the complications listed above are correctable to a great 1234567890();,: 1234567890();,: extent. Current day surgical management of coloboma-related retinal detachments has evolved to yield consistently good results. Cataract surgery in these eyes can pose a challenge due to a combination of microphthalmos and relatively hard lenses, resulting in increased risk of intra-operative complications. -
Novel Mutations in ALDH1A3 Associated with Autosomal Recessive Anophthalmia/ Microphthalmia, and Review of the Literature Siying Lin1, Gaurav V
Lin et al. BMC Medical Genetics (2018) 19:160 https://doi.org/10.1186/s12881-018-0678-6 RESEARCH ARTICLE Open Access Novel mutations in ALDH1A3 associated with autosomal recessive anophthalmia/ microphthalmia, and review of the literature Siying Lin1, Gaurav V. Harlalka1, Abdul Hameed2, Hadia Moattar Reham3, Muhammad Yasin3, Noor Muhammad3, Saadullah Khan3, Emma L. Baple1, Andrew H. Crosby1 and Shamim Saleha3* Abstract Background: Autosomal recessive anophthalmia and microphthalmia are rare developmental eye defects occurring during early fetal development. Syndromic and non-syndromic forms of anophthalmia and microphthalmia demonstrate extensive genetic and allelic heterogeneity. To date, disease mutations have been identified in 29 causative genes associated with anophthalmia and microphthalmia, with autosomal dominant, autosomal recessive and X-linked inheritance patterns described. Biallelic ALDH1A3 gene variants are the leading genetic causes of autosomal recessive anophthalmia and microphthalmia in countries with frequent parental consanguinity. Methods: This study describes genetic investigations in two consanguineous Pakistani families with a total of seven affected individuals with bilateral non-syndromic clinical anophthalmia. Results: Using whole exome and Sanger sequencing, we identified two novel homozygous ALDH1A3 sequence variants as likely responsible for the condition in each family; missense mutation [NM_000693.3:c.1240G > C, p. Gly414Arg; Chr15:101447332G > C (GRCh37)] in exon 11 (family 1), and, a frameshift mutation [NM_000693.3:c. 172dup, p.Glu58Glyfs*5; Chr15:101425544dup (GRCh37)] in exon 2 predicted to result in protein truncation (family 2). Conclusions: This study expands the molecular spectrum of pathogenic ALDH1A3 variants associated with anophthalmia and microphthalmia, and provides further insight of the key role of the ALDH1A3 in human eye development. -
