Neuroblastoma, a tumor of post-ganglionic sympathetic neurons, may be associated with a variety of genetic defects and congenital malformations (1). We report a case of neuroblastoma (NB) stage IV-S (2) in an infant with bilateral microphthalmia and other ocular malformations.

Kenny-Caffey syndrome 2 (KCS2) is a rare cause of hypoparathyroidism, inherited in an autosomal dominant mode, resulting from pathogenic variants of the gene, which is implicated in intracellular pathways regulating parathormone (PTH) synthesis and skeletal and parathyroid gland development. : The case of a boy is reported, presenting with the characteristic and newly identified clinical, biochemical, radiological, and genetic abnormalities of KCS2. : The proband had noticeable dysmorphic features, and the closure of the anterior fontanel was delayed until the age of 4 years.

Purpose: We present the case of a newborn with right anophthalmia, left congenital cystic eye, and two novel variants in the gene. This report provides a comprehensive discussion of the clinical presentation, management strategies, and long-term follow-up for this rare condition.
Methods: A thorough ophthalmic examination was performed.

A man in his early 20s was referred for refractive surgery evaluation. His best corrected distance visual acuity was 20/60 in both eyes. Preoperative manifest refraction was +13.

Microphthalmia, anophthalmia and coloboma (MAC) comprise a highly heterogeneous spectrum of congenital ocular malformations with an estimated incidence of 1 in 5000 to 1 in 30 000 live births. Although there is likely to be a genetic component in the majority of cases, many remain without a molecular diagnosis. Netrin-1 was previously identified as a mediator of optic fissure closure from transcriptome analyses of chick and zebrafish and was shown to cause ocular coloboma when knocked out in both mouse and zebrafish.

Purpose: Visual System Homeobox 2 () is a transcription factor expressed in the developing retina that regulates tissue identity, growth, and fate determination. Several mutations in the gene exist in mice, including a spontaneous nonsense mutation and two targeted missense mutations originally identified in humans. Here, we expand the genetic repertoire to include a reporter allele ( ) designed to express beta-Galactosidase (bGal) and simultaneously disrupt function (knock-in/knock-out).
