Clinical description

Affected babies are born in a collodion membrane. They also display ectropion and eclabium and a limited joint mobility. After the shedding of the membrane, patients present with mild scaling.


SCHB is due to mutations in the TGM1, ALOXE3 or ALOX12B genes encoding respectively transglutaminase 1, involved in the cornification of the stratum corneum, and arachidonate 3 and 12(R) lipoxygenases involved in lipid metabolism. Transmission is autosomal recessive.
