Hypohidrotic ectodermal dysplasia with hypothyroidism and ciliary dyskinesia

Other Names: HEDH syndrome; Hypohidrotic ectodermal dysplasia with hypothyroidism; Ectodermal dysplasia hypohidrotic with hypothyroidism and ciliary dyskinesia; Hypohidrotic ectodermal dysplasia - hypothyroidism - ciliary dyskinesia; ANOTHER syndrome

Hypohidrotic ectodermal dysplasia with hypothyroidism and ciliary dyskinesia is a rare condition characterized by alopecia (hair loss); nail dystrophy (abnormal development of the nails); ophthalmic (eye-related) complications; thyroid dysfunction (primary hypothyroidism); hypohidrosis; ephelides (freckles); enteropathy (disease of the intestine); and respiratory tract infections due to ciliary dyskinesia.

These features have lead to the acronym ANOTHER syndrome as an alternative name for the condition.
