Currently, autosomal recessive congenital ichthyosis (ARCI) in humans is associated with mutations in genes including TGM1 (MIM*190195), ABCA12 (MIM *607800), ALOXE3 (MIM *607206), ALOX12B (MIM*603741), ABHD5 (MIM *604780), NIPAL4 (MIM *609383), CYP4F22 (MIM*611495), and SLC27A4/Fatp4 (MIM *604194) related to this study [38]. Here, SLC27A4 is linked to autosomal recessive congenital ichthyosis.
