Steroid resistance
Why do steroids fail to suppress inflammation in some autoimmune diseases? We identify steroid responsive genome elements proximal to the chemokine CCL20.

Epidermal differentiation
We identify a key role for a calmodulin-like protein in regulation of terminal epidermal differentiation.
Genes and Development
Long noncoding RNAs
We performed a genome-wide CRISPR interference screen in human epidermal keratinocytes to identify a novel long noncoding RNA, PRANCR, that regulates epidermal tissue homeostasis.
Genome Research
Genome editing in skin
In our review, we highlight advances in wound healing and gene correction therapies in human skin.
Science
Becker's nevus
Postzygotic Mutations in Beta-Actin Are Associated with Becker's Nevus and Becker's Nevus Syndrome
Journal of Investigative Dermatology (2017)
Becker's nevus is a common hamartoma affecting 1 in 200 males, and involves overgrowth of epidermis, hair, and smooth muscle. Using exome sequencing, we found novel mutations in the ACTB gene that underlie this condition.
Calmodulin-like proteins
CALML5 is a ZNF750- and TINCR-induced protein that binds stratifin to regulate epidermal differentiation
Genes and Development (2015)
Using RNA-sequencing of laser captured human epidermis we find that CALML5 is the most highly upregulated gene in differentiation. Using genetic, genomic, and proteomic approaches we describe how a calmodulin-like protein controls terminal skin differentiation.
Genetics of nevus sebaceus
Mosaic activating RAS mutations in nevus sebaceus and nevus sebaceus syndrome
Journal of Investigative Dermatology (2013)
Using whole exome sequencing, we identify activating oncogenic HRAS and KRAS mutations in nevus sebaceus, establishing this condition as a mosaic RASopathy.
