DYSTROPHIN [2 records]

Record 1 2002-04-26

English

Subject field(s)
  • Biochemistry
DEF

Protein (400 kD) from skeletal muscle that is missing in Duchenne muscular dystrophy.

OBS

Its exact role is not yet clear though it seems to be associated with the cytoplasmic face of the sarcolemma and T-tubules and may form part of the membrane cytoskeleton. There are sequence homologies with non-muscle [alpha]-actinin and with spectrin.

  • Biochimie
CONT

Une autre approche consiste à prélever des cellules autologues déficientes en un gène particulier, comme c'est le cas dans la dystrophie de Duchenne, dans laquelle les cellules musculaires du patient sont déficientes en dystrophine, et à leur transférer in vitro ce gène avant de les réimplanter dans les muscles du patient.

Subject field(s)
  • Nervous System
CONT

Becker dystrophy is like a less severe form of Duchenne dystrophy. Recently it was shown that DMD [Duchenne's muscular dystrophy] and BMD are due to defects of the same gene. The normal function of the gene is to enable muscle fibers to make a particular chemical substance, a protein called dystrophin. Muscle fibres in people affected with DMD are extremely deficient in dystrophin, in BMD the deficiency is less severe.

  • Système nerveux
CONT

La dystrophie de Becker [...] est considérée comme une variante bénigne de la myopathie de Duchenne. L'anomalie génique se situe sur le même locus C bras court du chromosome X (X p21) avec une transmission récessive liée à l'X. Sur le plan structural il n'existe pas, comme dans la dystrophie de Duchenne, un déficit complet en dystrophine; la dystrophine est présente mais en quantité insuffisante ou de structure anormale.
