At the time there were no known COL27A1 mutations that caused human disease; however, last month Jacqueline Hecht and her group from Houston published the first human COL27A1 mutation in Steel syndrome in the Puerto Rican population.steel

Whole-exome sequencing identified a homozygous missense variant p.(Gly697Arg) in COL27A1, in a family with Steel syndrome and no consanguinity. The identified variant appears to have arisen as a founder mutation in the Puerto Rican population.
