A 9-base pair deletion in COL1A1 in a lethal variant of osteogenesis imperfecta.

The Journal of biological chemistry - 25 Nov 1991

Hawkins J R, Superti-Furga A, Steinmann B, Dalgleish R

Abstract excerpt

A proband with lethal osteogenesis imperfecta has been investigated for the causative defect at the levels of collagen protein, mRNA, and DNA. Analysis of type I collagen synthesized by the proband's fibroblasts showed excessive post-translational modification of alpha 1(I) chains along the entire length of the helix. Oververmodification of alpha chains could be prevented by incubation of the cells at 30 rather...
