This form (ICH-2; severe) is characterized by severe flaking with large amounts of whitish to brown scales and secondary infections with Malassezia. PNPLA1 mutations cause autosomal recessive congenital ichthyosis in golden retriever dogs and humans Ichthyoses comprise a heterogeneous group of genodermatoses characterized by abnormal desquamation over the whole body, for which the genetic causes of several human forms remain unknown. A non-epidermolytic ichthyosis (NI) is typically characterised by a prominent granular layer, with the presence of numerous mitotic figures in the keratinocytes, with marked lamellar.
