Meet Brenna, a baby with Harlequin Ichthyosis

The disease is caused by mutations in the ABCA12 gene, which then causes the skin to lack a certain protein that helps it form. Both parents have to be a carrier for the mutation, which makes it a one in a million chance that the child will have this disease, according to Brenna's mom Courtney Westlake.
