The estimation of recurrence risks in monogenic disorders using flanking marker loci.

abstract：:We report two patients with suspected hereditary liability to pressure palsies. Neurophysiological studies showed a mixed axonal-demyelinating sensory-motor polyneuropathy with focal slowing of conduction velocities at the common sites of entrapment.

abstract：BACKGROUND:Sonic hedgehog (SHH) plays an important role in defining the anterior-posterior axis in the developing limbs. A highly conserved non-coding sequence about approximately 1 Mb upstream from the sonic hedgehog gene (SHH) was shown to be a long range regulator for SHH expression in the limb bud. Point mutations ...
