Abstract:
Spontaneous pneumothorax (SP) is a condition defined by abnormal gas accumulation in the chest cavity. Mutations of the collagen type III alpha 1 chain, COL3A1 gene, are primarily linked to vascular Ehlers-Danlos syndrome (vEDS); however, they can also contribute to structural changes in the tissue, like bullae of the lungs. In this case report, we present a young, thinly built boy who died due to a spontaneous pneumothorax. Post-mortem genetic testing revealed a novel COL3A1 mutation, likely contributing to the pathogenic events underlying death due to spontaneous pneumothorax. We recommend implementing genetic testing of correlative or causative genes in the context of SP.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
