Other dog models for human non-syndromic ichthyoses include Norfolk Terriers with an epidermolytic ichthyosis caused by a KRT10 variant [13], Bulldogs with ARCI caused by a NIPAL4 variant [14], and Jack Russell Terriers with another form of ARCI caused by a TGM1 variant [15]. This evidence concerns the gene NIPAL4 and autosomal recessive congenital ichthyosis.
