Novel ABCA12 mutations in harlequin ichthyosis: a journey from photo diagnosis to prenatal diagnosis.

Harequin ichthyosis is a severe autosomal recessive ichthyosis of congenital onset caused by biallelic mutations in the ABCA12 gene. We report two neonates of Indian origin with harlequin ichthyosis. The parents were retrospectively found to have novel mutations in ABCA12 gene after neonatal demise, which helped in providing prenatal diagnosis in subsequent pregnancies.
