    human abca12 wild-type allele is located in the vicinity of 2q35 and is approximately 207 kb in length. this allele, which encodes glucosylceramide transporter abca12 protein, plays a role in both the membrane localization of glucosylceramide and other lipids in lamellar granules and in cholesterol transport. mutation of the gene is associated with autosomal recessive congenital ichthyosis (arci) types 4a and 4b (harlequin).
  • Lamellar Ichthyosis

    a very rare, autosomal recessive inherited skin disorder present at birth. it is characterized by the presence of a transparent membrane encasing the newborn. this membrane sheds in about two weeks after birth to reveal generalized scaling and skin erythema.
  • Sebaceous Hyperplasia

    enlargement of the sebaceous glands.
  • Senile Sebaceous Hyperplasia

    a hyperplasia of the sebaceous glands. it is usually seen as small yellow papules in the face of middle aged-older population.
