The disease locus in this family was mapped to 6p21.2, the region of the RDS/peripherin gene.     ///    "This study describes a new RDS/peripherin mutation for BPD and provides the first combined genetic-pathological study of this condition, to our knowledge. "    ///    "Further analysis identified a G-->A change at nucleotide position 637 of RDS/peripherin, predicting a novel Cys213Tyr substitution in all affected members of the family. "
