Summary: Using exome sequencing, we identified the first high myopia case with hemizygous ARR3-related mutation in a male patient, expanding the variant spectrum in ARR3 and providing additional information for genetic counseling, prenatal testing, and diagnosis. Additionally, we characterized the nonsense-mediated decay of the ARR3 mutant mRNA and discussed the possible underlying pathogenic mechanisms.

Summary: This study identified a novel frameshift variant of PAX9 causing nonsyndromic oligodontia in a Chinese family. The variant is pathogenic and may affect protein stability or folding. Functional studies demonstrated reduced transcription activity and protein production. These findings provide new insights into the role of PAX9 frameshift variants and expand the pathogenic spectrum of PAX9 variants.

Summary: This study aims to explore the association between clinical presentation and genotype in a Donnai-Barrow syndrome (DBS) patient. The patient, initially diagnosed with early-onset high myopia (eoHM) from a healthy Chinese family, was tested using whole exome sequencing and the results were validated among other family members using Sanger sequencing. Two novel variations in the LRP2 gene were found to be strongly associated with the typical clinical features of DBS patients. This study extends the genotypic spectra for LRP2-DBS and enhances the ability of physicians to predict, diagnose, and conduct gene therapy for DBS.

Summary: To identify susceptibility genes of Schizoaffective disease (SAD) with autonomic dominant inheritance, a family group from Henan province with high incidence of SAD was recruited. Genotype detection was performed using a genome-wide high-density SNP chip, and linkage analysis was conducted to obtain the nonparametric linkage (NPL) value, corresponding P value, and LOD value. The analysis identified a significant linkage signal on chromosome 19, with the candidate region of 19p13.3-13.2.

Summary: This study identified, for the first time, the influencing factors associated with high myopia in Chinese college students, including vessel density of the inner retina at the macula, vessel density of the radial peripapillary capillary at the optic disc, smartphone usage time, continuous near work time, and sleeping after midnight. A prediction model based on these factors was proposed to calculate the likelihood of a Chinese college student developing high myopia, which could be used to recommend lifestyle improvement and medical intervention.

Summary: We investigated genetic variations in a cohort of 113 families with nonsyndromic early-onset high myopia from northwestern China and identified sixteen potentially pathogenic variants in eight of seventeen causative genes for high myopia. These newly identified genetic variations expand the genetic and clinical spectra of high myopia and provide evidence for the contribution of ARR3, NDUFAF7, TNFRSF21, and ZNF644 genes to hereditable high myopia.

Summary: In this study, a novel de novo heterozygous variation in the EP300 gene was identified in a patient initially diagnosed with eoHM-RSTS. The reduced mRNA expression level of the EP300 gene suggested that this variant had an effect on gene function. The findings of this study expand the genotypic spectrum for EP300-RSTS and provide valuable information for physicians in predicting, diagnosing, counseling, and treating EP300-RSTS.

Summary: This study aimed to determine the annual incidences and rates of progression of myopia and high myopia in Chinese schoolchildren and explore the possible cause-specific risk factors for myopia. The results showed that both the annual incidence and progression rates of myopia and high myopia were high, especially after grade 3. Therefore, monitoring the hyperopic refraction of children before primary school is important to prevent the onset of myopia and high myopia.

Summary: This study elucidates the genetic background of early-onset high myopia (eoHM) and the characteristics of ARR3-associated MYP26. It reveals that ARR3 is the most frequently implicated gene for Mendelian eoHM, with mutations leading to mild cone impairment and progression to pathologic myopia.

Summary: Mutations in MYRF gene are associated with high hyperopia and may contribute to the development of angle closure glaucoma. MYRF is highly expressed in the ciliary body and ganglion cell layer, and mutations in MYRF result in elevated intraocular pressure and thinning of the retinal nerve fiber layer.

Summary: This study describes the variant landscape of 15 genes responsible for corneal dystrophies (CDs) in Chinese families. Pathogenic or likely pathogenic variants were detected in 4 of the 15 genes in 30 of the 37 families with CDs. Comparative analysis revealed that some previously reported variants are unlikely causative of CDs. The study highlights the importance of understanding frequently misinterpreted variants in genomic medicine.

Summary: During the COVID-19 pandemic, the onset of Leber hereditary optic neuropathy (LHON) changed and new risk factors were identified. The age of LHON onset decreased significantly during this period, and secondhand smoke exposure and mask-wearing were found to be independent risk factors for younger LHON onset.

Summary: Variants in FDXR are associated with autosomal recessive auditory neuropathy and optic atrophy, expanding to retinal dystrophy. This study identified 11 unrelated patients with biallelic pathogenic or likely pathogenic FDXR variants, including 10 novel missense variants. Clinical data revealed severe optic atrophy, retinal degeneration, and various retinal vascular abnormalities in these patients. Biallelic FDXR variants are a common cause of congenital or early-onset severe retinal dystrophy, particularly in patients with optic atrophy and retinal dystrophy in early childhood.

Summary: Knobloch syndrome is an autosomal recessive disorder characterized by high myopia, retinal detachment, and occipital skull defects. Mutations in the COL18A1 gene have been identified to cause KNO1. Here, we successfully generated a human induced pluripotent stem cell (hiPSC) line from the peripheral blood mononuclear cells (PBMCs) of a KNO patient caused by COL18A1 biallelic pathogenic variants, and this iPSC model offers a precious disease model to study the pathological mechanism and possible treatment of KNO in vitro.

Summary: This study analyzed the clinical characteristics and prognosis of autosomal dominant retinopathy (ADRP) and autosomal recessive retinopathy (ARRP) associated with NR2E3. Nine pathogenic variants/likely pathogenic variants in NR2E3 were detected, including five novel variants. Follow-up data showed schisis/atrophy in the macula and retinal degeneration initiation around the vascular arcades in both ADRP and ARRP, but ADRP patients had better visual acuity and later onset age compared to ARRP patients.

Summary: This study aimed to identify the contribution of OPN1LW to early-onset high myopia (eoHM) and the molecular basis underlying eoHM with or without colorblindness. Unique haplotypes and truncation variants in OPN1LW were found exclusively in 68 of 1226 families with eoHM, but not in 9304 families with other visual diseases. Four classes of variants were identified, which cause partial or complete loss of red photopigments. The study provides evidence that eoHM with or without colorblindness are caused by different variants in OPN1LW.

Summary: This study reports a new autosomal dominant ocular syndrome (BAMD) syndrome caused by monoallelic MAB21L1 pathogenic variants, which is completely different from COFG syndrome caused by biallelic variants in MAB21L1. The study suggests that heterozygous pathogenic variants in MAB21L1 account for the AD BAMD syndrome, and c.152 nucleotide is likely a mutation hot spot, with the residue p.Arg51 being critical for MAB21L1.
