The dermis of Col5a1tm1Rjw/Col5a1+ mice contains poorly organized and less densely packed fibers

cardiovascular system
• ascending and descending aortas from 12-week old mutants exhibit decreased aortic stiffness and breaking strength

integument
• exhibit a 50% decrease in type V collagen content in skin
• mice show alterations in type I collagen fiber composition in the dermis, but not the Achilles tendons, including a decrease in the beta1,2 dimers, cross-linked by an intramolecular aldol band and increase in gamma trimers, cross-linked by an intermolecular aldol bond
• dermis contains poorly organized and less densely fibers and contains a mixture of relatively normal symmetrical fibrils that are somewhat broader and larger in diameter and very large diameter and aberrant fibrils; the large aberrant fibrils contain no type V collagen
• exhibit a significant delay in dermal collagen accumulation between 4 and 8 weeks of age, however by 12 weeks the total quantity of dermal collagen is similar to wild-type
• dermis shows reduced density of dermal connective tissue
• skin is hyperextensible compared to wild-type, but there is no skin redundancy
• tensile strength of unwounded and wounded skin is reduced
