Two of the 4 living affected children showed more severe manifestations than any of the other patients in the pedigree. In the absence of either of those 2 features, the presence of an FBN1 mutation or a combination of systemic manifestations is required, for which there is a revised scoring system. Connective Tissue and Its Heritable Disorders: For most women, safe vaginal delivery is possible.

Complications include rapid progression of aortic root enlargement and aortic dissection or rupture during pregnancy, delivery, and the postpartum period.

In contrast, all 4 cases of liveborn trisomy 8 studied appeared to have arisen by a mechanism consistent with the postzygotic mitotic gain of the additional chromosome, a mechanism consistent with mosaicism.

Although some studies have explored the acute and chronic impact of this intervention, the literature is still lacking in information. Fibrillin-1 is essential for the proper formation of the extracellular matrix, including the biogenesis and maintenance of elastic fibers. EDS kyphoscoliotic form is caused by deficient activity of the enzyme procollagen-lysine, 2-oxoglutarate 5-dioxygenase 1, resulting from biallelic pathogenic variants in PLOD1.
