Human type VII collagen gene is found within this region in chromosome region 3p21.1.

The syndrome is thought to arise from a mutation of several collagen genes during fetal development.

COL21A1 is a collagen gene.

COL23A1 is a collagen gene.

They took a fragment of DNA that controlled the production of a collagen gene from the tiger and inserted it into a mouse embryo.

Yet the worm turns out to have 170 collagen genes.

Regardless, these disorders involve alterations (mutations) of the collagen gene, COL11A2.

COL24A1 is a collagen gene.

It has been proposed that Topo I may be directly involved in transcription of interstitial collagen genes [ 30].

However, other families do not show the linkage to the collagen gene.
