BACKGROUND:Psychiatric syndromes have polymorphic symptomatology, and are known to be heritable. Psychiatric symptoms (and even syndromes) often occur as part of the clinical presentation in rare Mendelian syndromes. Clinical exome sequencing reports may help with refining diagnosis and influence treatment decisions, in addition to providing a window into the biology of brain and behaviour. We describe a clinical audit of 12 individuals who sought treatment at our hospital, and for whom targeted sequencing was ordered. Three cases are discussed in detail to demonstrate correlations between genotype and phenotype in the clinic.METHODS:Targeted Next-Generation Sequencing (NGS) was done using Clinical Exome Panel (TruSight One, Illumina) covering coding exons and flanking intronic sequences of 4811 genes associated with known inherited diseases. Variants detected were classified according to the American College for Medical Genetics (ACMG) recommendation for standards of interpretation and reporting of sequence variations.RESULTS:Ten out of twelve cases had at least one pathogenic variant. In one of these cases, we detected a known pathogenic variant in MAPT gene in a suspected FTD case, which helped us to confirm the diagnosis. In another case, we detected a novel variant predicted to be deleterious in NF1 gene. Identification of this mutation suggested a change in treatment for the patient, that was of benefit. The same patient also harboured a novel variant in the TRIO gene. This gene may be involved in biological processes that underlie the patient’s psychiatric illness.CONCLUSIONS:The cases discussed here exemplify different scenarios under which targeted exome sequencing can find meaningful application in the clinic: confirming diagnosis (MAPT variant), or modifying treatment (NF1). We suggest that clinical exome sequencing can be a helpful addition to a clinician’s toolkit when there are expediting factors to consider— such as early-onset, strong family history of mental illness, complex/atypical presentations and minor physical anomalies or neurocutaneous markers.

Introduction: We describe the phenotype of a variant lattice corneal dystrophy (LCD) potentially caused by a novel variant c.1772C>T p.(Ser591Phe) in exon 13 of the transforming growth factor beta-induced (TGFBI) gene. Case report: The proband, a 71-year-old woman referred because of bilateral LCD, first seen at the age of 65 years, with recent progressive symptoms, underwent a clinical ophthalmological examination, anterior segment optical coherence tomography and confocal microscopy. Additionally, three siblings and three children were examined. The identified TGFBI variant was screened in six family members using Sanger sequencing. A corneal dystrophy gene screen was performed for the proband. Translucent subepithelial irregularities and central to midperipheral stubby branching corneal stromal lattice lines, asymmetric between the right and the left eye, were visible and resulted in mild deterioration of vision in one eye. Genetic testing revealed a novel variant c.1772C>T in TGFBI, leading to the amino acid change p.(Ser591Phe). One daughter carried the same variant but had only thick stromal nerve fibres at the age of 49 years. The other family members neither had corneal abnormalities nor carried the variant. No keratoplasty is yet planned for the proband. Conclusions: We classify the novel variant in TGFBI as possibly pathogenic, potentially causing the late-onset, asymmetric variant LCD. Our findings add to the growing number of TGFBI variants associated with a spectrum of phenotypes of variant LCD.

Infectious bursal disease (IBD), an immunosuppressive disease of young chickens, is caused by infectious bursal disease virus (IBDV). Novel variant IBDV (nVarIBDV), a virus that can evade immune protection against very virulent IBDV (vvIBDV), is becoming a threat to the poultry industry. Therefore, nVarIBDV-specific vaccine is much needed for nVarIBDV control. In this study, the VP2 protein of SHG19 (a representative strain of nVarIBDV) was successfully expressed using an Escherichia coli expression system and further purified via ammonium sulfate precipitation and size-exclusion chromatography. The purified protein SHG19-VP2-466 could self-assemble into 25-nm virus-like particle (VLP). Subsequently, the immunogenicity and protective effect of the SHG19-VLP vaccine were evaluated using animal experiments, which indicated that the SHG19-VLP vaccine elicited neutralization antibodies and provided 100% protection against the nVarIBDV. Furthermore, the protective efficacy of the SHG19-VLP vaccine against the vvIBDV was evaluated. Although the SHG19-VLP vaccine induced a comparatively lower vvIBDV-specific neutralization antibody titer, it provided good protection against the lethal vvIBDV. In summary, the SHG19-VLP candidate vaccine could provide complete immune protection against the homologous nVarIBDV as well as the heterologous vvIBDV. This study is of significance to the comprehensive prevention and control of the recent atypical IBD epidemic.
