research Autosomal Recessive Ichthyosis With Hypotrichosis Syndrome: Further Delineation Of The Phenotype

55 citations , April 2008 in “Clinical Genetics”

This report identifies a novel mutation in the ST14 gene in a female with autosomal recessive ichthyosis with hypotrichosis, highlighting similar features to previously reported cases.

research Autosomal Ichthyosis With Hypotrichosis Syndrome Displays Low Matriptase Proteolytic Activity and Is Phenocopied in ST14 Hypomorphic Mice

101 citations , October 2007 in “Journal of Biological Chemistry”

This study indicates that reduced activity of the matriptase-prostasin proteolytic cascade is likely the cause of human autosomal recessive ichthyosis with hypotrichosis, as demonstrated using a novel mouse model.
