1388:1461 ISMLTGLFGATAGTIFVYGKDIKTDLNTVRKNMGVCMQHDVLFSYLTTKEHLLLYGSIKVPHWTKTQLHEEVKR→M: In a mouse model for harlequin ichthyosis (HI), smooth skin (smsk) mutant mice show a pronounced perinatal lethal skin phenotype in 25% of the offspring and newborn mutant pups die within a few hours after birth, and appear severely dehydrated with dry cracking skin. Smsk homozygous mutants embryos show a normal appearance at 14.5 dpc, but at 16.5 dpc develop a partial absence of normal skin folds around the trunk and limbs, and by 18.5 dpc develop a taut, thick skin and limb contractures.
1996 G→D: In a mouse model for harlequin ichthyosis (HI), homozygous mice are embryonic lethal but occasionally pups are found in the first few hours after birth but die and are severely dehydrated and fail to suckle normally. Homozygous pups show hallmarks of HI desease including hyperkeratosis, abnormal extracellular lipid lamellae and defects in cornified envelope processing. At 14.5 dpc and 15.5 dpc homozygous embryos appear normal; however from 16.5 dpc onwards they are characterized by an absence of normal skin folds around the trunk and limbs. As development progressed, embryos develop a taut, thick epidermis and multiple contractures affecting the limbs. Late stage embryos are smaller.

292 E→V: Knockin new born mice are healthy and survive into adulthood without overt signs of respiratory distress. Knockin mice show a severe lung phenotype that begins with alveolar inflammatory cell infiltration at the early stage of the mouse life followed by aberrant lung remodeling with characteristics of diffuse parenchymal lung disease (DPLD)- and emphysema-like alveolar disruption in older mice.
