Abstract:
Conradi-Hünermann-Happle syndrome (X-linked dominant chondrodysplasia punctata, CDPX2 [Online Mendelian Inheritance in Man 302960]) is a rare genodermatosis that presents with blaschkolinear ichthyosis, cicatricial alopecia, chondrodysplasia punctata, asymmetric shortening of the bones, and cataracts. In this case report we describe a child presenting with a patterned alopecia in which supplementary signs and clinical examination of the mother led to the suspicion of Conradi-Hünermann-Happle syndrome. Mutation analysis revealed a heterozygous novel missense mutation, c.204G>T (p.W68C), in exon 2.
