Abstract excerpt
BACKGROUND: Harlequin ichthyosis (HI), one of the most severe genetic skin disorders, is autosomal recessively inherited. Mutations in ABCA12, which encodes ATP-binding cassette transporter A12 (ABCA12), are known to be the cause of HI. It is very difficult to make precise genetic diagnosis when an exon deletion mutation overlaps the site of another causative point mutation. This combination of mutations may lead...
