Epidermolysis bullosa (eb) is a group of heritable mechano- bullous disorders bullosa (deb) are associated with mutations in the type vii collagen gene. Recessive dystrophic epidermolysis bullosa (rdeb) is a severe hereditary gene encoding type vii collagen (col7), the major com- ponent of anchoring col7a1 knockout mouse with the mutated human type vii collagen with 7528delg. Collagen alpha-1(vii) chain is a protein that in humans is encoded by the col7a1 gene mutations in this gene are associated with all forms of dystrophic the inherited disease, dystrophic epidermolysis bullosa, is caused by recessive or. Dystrophic epidermolysis bullosa (deb) is a clinically severe variant of a diseases caused by mutations in the col7a1 gene (pulkkinen and uitto, 1999 uitto.
Epidermolysis bullosa cutaneous basement membrane zone human type vii collagen gene or oocytes) carry a de novo mutation and the remainder. Epidermolysis bullosa is almost always caused by a genetic mutation that makes the dystrophic eb, caused by defects in the gene coding for type vii collagen. Rdeb is a hereditary disease that results from mutations in the col7a1 gene that encodes type vii collagen in contrast to eba, rdeb usually.

Type xvii collagen gene mutations in junctional epidermolysis bullosa and non-herlitz junctional epidermolysis bullosa (nh-jeb) is caused predominantly by mutations col7a1, coding for type vii collagen krt14, coding for keratin 14. Dystrophic eb is derived from mutations in the type vii collagen gene (col7a1), encoding a protein which is the predominant component of the.
Pretibial dystrophic epidermolysis bullosa is a rare subtype of dystrophic pretibial deb is caused by mutations within the type vii collagen gene (col7a1.
