Objective: To use array comparative genomic hybridization (array-CGH) and multiplex ligation-dependent probe amplification (MLPA) to detect unbalanced rearrangements in 4 cases suspected to have chromosome disease but were undetected with conventional karyotype analysis, and to assess the applicability of array-CGH and MLPA for detection of unbalanced translocation.
Methods: Genomic DNA was extracted with standard procedures. All cases were analyzed by array-CGH and subtelomeric MLPA.
Results: All of the cases were identified to have unbalanced translocations by array-CGH analysis, among which 3 were consistent with subtelomeric MLPA analysis. For the remaining one, its chromosomal abnormality was not detected by MLPA as the imbalance has occurred outside of target regions.
Conclusion: Both array-CGH and MLPA techniques can complement conventional karyotyping for detecting unbalanced translocations. The combination features both high resolution and efficiency for clinical use.

Background: Patients with neuromuscular diseases (NMD) have undergone considerable technological progress in terms of diagnosis and treatment over the past few years. Specifically, next-generation sequencing (NGS) has significantly expanded genetic diagnosis. Despite this, some patients remain undiagnosed and therefore without access to specific treatments.

We report the first case of pleural mesothelioma (PM) occurring in a child affected by NF2-related schwannomatosis (NF2-SWN) and without any history of environmental exposure to asbestos. Mesothelioma is a rare secondary tumor in brain cancer patients and the association with NF2-SWN has been described only in a few anecdotal cases and never in the pediatric field. NF2-SWN is an autosomal dominant disease caused by inactivating germline mutations of the tumor suppressor gene, one of the most common mutations associated with human primary mesothelioma too.

Hypomyelinating leukodystrophies are a heterogeneous group of disorders characterized by abnormal myelin formation in the central nervous system. Thanks to the increased use of NGS, a growing number of pathogenic single nucleotide variants in have recently been reported to be responsible for hypomyelinating leukodystrophy 18 (HLD18), a rare and severe autosomal recessive form. is a small gene (4 exons and 17 kb) encoding 4-dihydroceramide desaturase, which catalyzes the final step in ceramide biosynthesis.

Prader-Willi syndrome (PWS) is an uncommon genetic disorder caused by the lack of expression of a cluster of genes located in the 15q11.2q13 region, which are normally expressed only from the paternally-inherited allele due to genomic imprinting. PWS can result from a deletion of the 15q11.
