Harlequin-type ichthyosis – Wikipedia

Management of survivors is similar to management of severe CIE and includes use of emollients, keratolytics, and retinoids.

Nutritional support with tube feeds is essential until eclabium resolves and infants can begin nursing. Plaques, measuring up to 4 or 5 cm on a side, have a diamond-like configuration resembling the suit of a harlequin clown.

Influence of nutrition on growth and development of a long-surviving harlequin fetus. In the past, the disorder was nearly always fatal, whether due to dehydrationinfection sepsisrestricted breathing due to the plating, or other related causes. Goldsmith agreed with the distinctness of this entity from lamellar ichthyosis. Genotype-phenotype correlation have been poorly elucidated but most mutations underlying HI are thought to lead to severe loss of ABCA12 protein function affecting important nucleotide-binding fold domains or transmembrane domains resulting in impaired lipid barrier function.

When they survive, the collodion membrane sheds after a few weeks and transforms into severe erythroderma with severe scaling and persistent ectropion. Pigmentation disordersTemplate: Harlequin ichthyosis, [1] hyosis fetalis, keratosis diffusa fetalis, harlequin fetus, [2]: Alrequin ICD – The infants were covered with an enormous horny shell, similar to armor, with deep creases which fragmented the hard surface into large polygonal plates.


Costello syndrome Kindler syndrome Laryngoonychocutaneous syndrome Skin fragility syndrome. Most of the mutations in HI patients were truncation mutations, and homozygosity or compound heterozygosity for icctiosis mutations in ABCA12 always resulted in the HI aroequin. Babies who survive into infancy and beyond develop skin changes resembling severe nonbullous congenital ichthyosiform erythroderma see summary by Rajpopat et al.

Lawlor described an infant who survived to 2 and a half years, progressing to the picture of nonbullous ichthyosiform erythroderma. Harlequin-type ichthyosis is due to mutations arlequij the ABCA12 genes. The documents contained in this web site are presented for information purposes only. ABCA12 is thought to be a lipid transporter in ictiosos necessary for lipid transport into lamellar granules during the formation of the lipid barrier.

For a general phenotypic description and a discussion of genetic heterogeneity of autosomal recessive congenital ichthyosis, see ARCI1 Chorionic villus karyotyping of the fetus had revealed a nonmosaic chromosome 2 trisomy, whereas postnatal peripheral blood karyotype was normal, indicating trisomic rescue.

Ophthalmology consultation is useful for the early management of ectropionwhich is initially pronounced and resolves as scales are shed.
