Hidrotic ectodermal dysplasia: study of a large Chinese pedigree. 1977

K Rajagopalan, and C H Tay

Hidrotic ectodermaldysplasia was found, to our knowledge, for the first time in a Chinese family in Malaysia, and it affected 15 members in five generations. The disease, which is transmitted as a non-sex-linked autosomal dominant trait, presumably originated from southern China. All 15 members had the typical nail, hair, and skin lesions, and we observed three different types of nail defects. Scalp alopeica was more extensive in the female members while keratoderma of the palms and soles was more notable in the male members. The nail and skin lesions also became severer with age. Except for the infectious eczematoid dermatitis present in the propositus, none had other skin or systemic disorders. All were relatively healthy and had normal life expectancies;

D008296	Malaysia	A parliamentary democracy with a constitutional monarch in southeast Asia, consisting of 11 states (West Malaysia) on the Malay Peninsula and two states (East Malaysia) on the island of BORNEO. It is also called the Federation of Malaysia. Its capital is Kuala Lumpur. Before 1963 it was the Union of Malaya. It reorganized in 1948 as the Federation of Malaya, becoming independent from British Malaya in 1957 and becoming Malaysia in 1963 as a federation of Malaya, Sabah, Sarawak, and Singapore (which seceded in 1965). The form Malay- probably derives from the Tamil malay, mountain, with reference to its geography.

D004476	Ectodermal Dysplasia	A group of hereditary disorders involving tissues and structures derived from the embryonic ectoderm. They are characterized by the presence of abnormalities at birth and involvement of both the epidermis and skin appendages. They are generally nonprogressive and diffuse. Various forms exist, including anhidrotic and hidrotic dysplasias, FOCAL DERMAL HYPOPLASIA, and aplasia cutis congenita.
