Oculoauriculovertebral spectrum (OAVS) is a clinically and genetically heterogeneous congenital disorder. We performed high density oligonucleotide array-CGH on 86 OAVS patients and identified in 11 patients 12 novel genomic rearrangements (4 deletions and 8 duplications) ranging in size from 2.7 kb to 2.3 Mb. We discuss the potential pathogenic role of these chromosomal aberrations, and describe new candidate regions for OAVS.

Purpose: To evaluate the growth, management, and outcomes of epibulbar dermolipomas over a 5-year follow-up period.
Methods: This was a retrospective chart review of epibulbar dermolipoma patients with a minimum follow-up of 5 years, which analyzed the changes in size, refractive errors (spherical equivalent), best-corrected visual acuity, histology, and surgical outcomes.
Results: A total of 61 eyes of 53 patients (32 females) with an average presenting age of 4.

Background: Goldenhar syndrome is a clinically heterogeneous disorder defined by a rare combination of congenital anomalies-an eye abnormality, in addition to two of the following three: ear anomalies, mandibular malformations, and vertebral defects. Notably, children with Goldenhar syndrome present with a high incidence of cervical spine malformations.
Clinical Case: In this report, we present an unusual case of a 15-year-old child with Goldenhar syndrome, who additionally presents with some clinical features of VACTERL syndrome.

Can some metabolic one-carbon cycle linked diseases be prevented? The impact of treating hypo-fertile couples carrying MTHFR SNPs with folic acid and 5-MTHF on outcomes in the offspring: a case retrospective series.

Purpose: In our practice, testing hypo-fertile patients for circulating homocysteine (Hcy) and the two principal MTHFR SNPs (677C > T and 1298A > C) has been routine for the past 7 years. Couples carrying a genetic background known to be associated with the disease were proposed treatment regimens consisting of 5-methyl tetrahydrofolate (5-MTHF) together with nutritional support of the one-carbon cycle (1-CC). Some patients preferred to continue with folic acid (FA) as prescribed by their referring gynecologist/obstetrician: this gave us the opportunity to compare outcomes between the two groups of patients.

Goldenhar syndrome, also known as oculo-auriculo-vertebral dysplasia or hemifacial microsomia, is a rare congenital anomaly involving the first and second branchial arches. In this case report, we present a distinctive instance of a 43-year-old male with Goldenhar syndrome who presented with nausea and recurrent bilious vomiting. Initial diagnostic imaging raised concerns about pancreatitis, leading to a comprehensive evaluation that revealed gallstone pancreatitis as the cause of his symptoms.
