Causing severe facial and neural-tube defects, Grhl2 knockout is embryonically lethal in mice,17,20 and mutant zebrafish display inner-ear defects and abnormal swimming positions.18 In contrast, Grhl1−/− mice show hair loss and palmoplantar keratoderma, as well as abnormal desmosome cell junctions and dysregulated terminal differentiation in keratinocytes.21 Moreover, Grhl3−/− embryos fail to establish a normal epidermal barrier and display defective embryonic wound repair.22 Thus, unlike for GRHL1 and GRHL3, there is currently a lack of data associating GRHL2 with skin pathology. In this report, however, we have identified two families in which affected subjects have developmental defects affecting skin, oral mucosa, and teeth (as well as hearing and lungs), thus implicating GRHL2 in an autosomal-recessive ectodermal dysplasia syndrome.","tracks":[{"project":"2_test","denotations":[{"id":"25152456-12175488-2045829","span":{"begin":43,"end":45},"obj":"12175488"},{"id":"25152456-12393799-2045830","span":{"begin":163,"end":165},"obj":"12393799"},{"id":"25152456-23813623-2045830","span":{"begin":163,"end":165},"obj":"23813623"},{"id":"25152456-17921507-2045831","span":{"begin":304,"end":306},"obj":"17921507"},{"id":"25152456-21610158-2045831","span":{"begin":304,"end":306},"obj":"21610158"},{"id":"25152456-24131873-2045831","span":{"begin":304,"end":306},"obj":"24131873"},{"id":"25152456-17921507-2045832","span":{"begin":487,"end":489},"obj":"17921507"},{"id":"25152456-20654612-2045832","span":{"begin":487,"end":489},"obj":"20654612"},{"id":"25152456-21610158-2045833","span":{"begin":569,"end":571},"obj":"21610158"},{"id":"25152456-18288204-2045834","span":{"begin":748,"end":750},"obj":"18288204"},{"id":"25152456-15831758-2045835","span":{"begin":868,"end":870},"obj":"15831758"}],"attributes":[{"subj":"25152456-12175488-2045829","pred":"source","obj":"2_test"},{"subj":"25152456-12393799-2045830","pred":"source","obj":"2_test"},{"subj":"25152456-23813623-2045830","pred":"source","obj":"2_test"},{"subj":"25152456-17921507-2045831","pred":"source","obj":"2_test"},{"subj":"25152456-21610158-2045831","pred":"source","obj":"2_test"},{"subj":"25152456-24131873-2045831","pred":"source","obj":"2_test"},{"subj":"25152456-17921507-2045832","pred":"source","obj":"2_test"},{"subj":"25152456-20654612-2045832","pred":"source","obj":"2_test"},{"subj":"25152456-21610158-2045833","pred":"source","obj":"2_test"},{"subj":"25152456-18288204-2045834","pred":"source","obj":"2_test"},{"subj":"25152456-15831758-2045835","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#ec93e4","default":true}]}]}}
