Abstract
A 7-year-old boy was diagnosed and treated for familial exudative vitreoretinopathy. Genetic testing revealed a 16p13.11 microdeletion and unbalanced translocation causing 11q deletion syndrome. This is the first report describing retinal findings associated with this combination of genetic alterations. Patients with 11q deletion syndrome or 16p13 microdeletions should undergo ophthalmologic examination. [J Pediatr Ophthalmol Strabismus. 2017;54:e71-e74.].

Abstract
Proteins in the aqueous humor (AH) are important in the induction of cataract development. The identification of cataract-associated proteins assists in identifying patients and predisposed to the condition and improve treatment efficacy. Proteomics analysis has previously been used for identifying protein markers associated with eye diseases; however, few studies have examined the proteomic alterations in cataract development due to high myopia, glaucoma and diabetes. The present study, using the isobaric tagging for relative and absolute protein quantification methodology, aimed to examine cataract-associated proteins in the AH from patients with high myopia, glaucoma or diabetes, and controls. The results revealed that 445 proteins were identified in the AH groups, compared with the control groups, and 146, 264 and 130 proteins were differentially expressed in the three groups of patients, respectively. In addition, 44 of these proteins were determined to be cataract‑associated, and the alterations of five randomly selected proteins were confirmed using enzyme-linked immunosorbent assays. The biological functions of these 44 cataract-associated proteins were analyzed using Gen Ontology/pathways annotation, in addition to protein‑protein interaction network analysis. The results aimed to expand current knowledge of the pathophysiologic characteristics of cataract development and provided a panel of candidates for biomarkers of the disease, which may assist in further diagnosis and the monitoring of cataract development.

A case of Jacobsen syndrome with multifocal white matter lesions. Clin Imaging 2016; 40:705-6.

Abstract
Jacobsen syndrome is a rare disorder caused by partial deletions of the long arm of chromosome 11. The phenotype is variable with involvement of multiple organ systems, resulting in congenital heart defects, blood dyscrasias, and impaired growth. We describe a case of a 30-year-old man with multiple ophthalmic manifestations and brain magnetic resonance imaging (MRI) that was remarkable for multiple T2-hyperintense subcortical white matter lesions. It is important to be aware that patients with Jacobsen syndrome may have nonspecific white changes seen on MRI.

Abstract
Interstitial deletions of the long arm of chromosome 11 are rare, and they could be assumed as non-recurrent chromosomal rearrangements due to high variability of the size and the breakpoints of the deleted region. The exact region of the deletion was difficult to be determined before the use of molecular cytogenetic techniques such as array comparative genomic hybridization (aCGH). Here, a 13-year old boy with severe learning difficulties, mental retardation and mild heart defects is described. Conventional G-band karyotyping was performed and it is found that the patient is a carrier of a de novo interstitial deletion on the long arm of chromosome 11, involving 11q14 and 11q22 breakpoints. Further investigation, using aCGH, specified the deleted region to 11q14.2-11q22.1. There was a difficulty in correlating the genotype with the phenotype of the patient due to lack of similar cases in literature. More studies should be done in order to understand the genetic background that underlies the phenotypic differences observed in similar cases.

Abstract
BACKGROUND Interstitial deletions of chromosome 11 long arm are rarely observed and the associated phenotype ranges from normal to severe, depending on the position and size of the deletion and on the presence of unmasked recessive genes on the normal homologous. To our knowledge 32 cases are reported in literature with three family cases. Phenotype-genotype correlation is not very clear and the most common features are characteristic facial dysmorphisms, palate anomalies and developmental delay. Growth retardation is not typical and other major malformations are reported in some cases. CASE PRESENTATION We described a child with 11q interstitial deletion diagnosed at birth with hypotonia and minor dysmorphisms using standard cytogenetic techniques; array CGH was subsequently performed to define the deletion at a molecular level. CONCLUSIONS This case gave us the opportunity to attempt a genotype-phenotype correlation reviewing the literature and to describe a rehabilitative program that improved the development perspectives of this child.

Abstract
BACKGROUND Retinoschisis, or retinal lamellar splitting, can occur in a number of hereditary conditions. The most common cause of congenital or childhood onset retinoschisis is the clinical entity known as juvenile retinoschsis, which is caused by mutations in the X-linked retinoschisis 1 gene. Genes other than X-linked retinoschisis 1 gene have rarely been implicated in association with hereditary retinoschisis. METHODS We describe a 9-year-old male who presented with several phenotypic features associated with partial monosomy of chromosome 6q and partial trisomy of chromosome 11q, including myelomeningocele, mental and growth retardation, seizures, microcephaly, scoliosis, and facial dysmorphisms, as well as novel ocular findings including bilateral retinoschisis and hyperopia. RESULTS This case report highlights the necessity for a detailed ophthalmic examination of patients with both 6q deletions as well as 11q duplications to ensure accurate and timely diagnosis and treatment of the complications associated with the described ocular conditions.

Submicroscopic interstitial deletion of chromosome 11q22.3 in a girl with mild mental retardation and facial dysmorphism: Case report. Mol Cytogenet 2011; 4:17.

Abstract
BACKGROUND Except for terminal deletions that lead to Jacobsen syndrome, interstitial deletions involving the long arm of chromosome 11 are not frequently reported. A clinically distinct phenotype is usually observed in these cases, and no clear genotype-phenotype correlation is proposed. RESULTS Here we present a case study of a 5-year-old girl with de novo submicroscopic deletion of chromosome 11q22.3 with mild mental retardation and facial dysmorphism. A standard cytogenetic analysis did not reveal any structural aberrations. In contrary, array-CGH analysis indicated a small deletion of 11q22.3. DISCUSSION To our knowledge, this is the smallest 11q22.3 deletion reported in literature, containing nine RefSeq genes. Although none of the deleted genes are obvious candidates for the features observed in our patient, genes CUL5 and SLN could play a key role in the features described.
