On the other hand, homozygo mgΔ animals die of MFS-like vascular plitns wh the first month of postnatal life as a rult of substantial fibrill 1 ficiency. Homozygo Tsk embryos generate utero at ∼8 d of gtatn of unknown (Green et al.

DiscsnOur current unrstandg of the role of fibrill 1 microfibrils nnective tissue physlogy is based primarily on the study of human mutatns MFS and homologo gene targetg the moe (Dietz and Pyerz 1995; Ramirez et al. Therefore, the cultured system should be viewed more as a bchemil bdg assay to tt homopolymerizatn vers heteropolymerizatn rather than a physlogil mol of microfibril assembly.
The phenotypic severy of Tsk and mgΔ homozygot is dramatilly different. Tsk/Tsk embryos produce a homogeno populatn of longer molecul normal abundance; mgΔ/mgΔ mice produce a homogeneo populatn of shorter molecul a much lower abundance.
