Insights
Harlequin ichthyosis, a severe genetic skin disorder, affects 1 in a million newborns. This case highlights a rare instance in a non-consanguineous family, noting maternal chickenpox during pregnancy.
Area of Science:
- Genetics
- Dermatology
- Neonatology
Background:
- Harlequin ichthyosis is a rare, severe congenital ichthyosis with a distinct phenotype.
- It occurs in approximately 1 in 1 million births, with over 100 cases reported.
- The condition results from mutations in the ABCA12 gene, crucial for lipid transport and stratum corneum development.
Observation:
- This article presents a case of a harlequin baby born to non-consanguineous parents.
- The mother had a history of chickenpox during the first trimester of pregnancy.
- The infant exhibited the characteristic severe physical presentation of harlequin ichthyosis.
Findings:
- The case underscores the genetic basis of harlequin ichthyosis, linked to ABCA12 gene mutations.
- Management typically involves supportive care and retinoid derivatives.
- The prognosis remains poor, with most affected infants succumbing during the neonatal period.
Implications:
- This case contributes to the limited literature on harlequin ichthyosis, particularly regarding potential environmental factors like maternal infections.
- It emphasizes the importance of genetic counseling and early diagnosis in affected families.
- Further research may explore the interplay between genetic predisposition and potential teratogenic exposures in congenital ichthyosis.
Abstract:
Harlequin ichthyosis is a rare, severe form of congenital ichthyosis characterised by distinct physical appearance of the infant. It has occurrence of 1 in 1 million births and over 100 cases have been reported so far. It is caused by mutation in ABCA12 gene involved in lipid transport leading to profound thickening of stratum corneum. The mainstay of management relies on supportive care & administration of retinoid derivatives. Outcome is usually fatal and most of the babies die during neonatal period. In this article, we report a case of harlequin baby born of non-consanguineous marriage with history of chicken pox in the mother during first trimester of pregnancy.
