We report on a family with a not earlier described multiple congenital malformation. Several male family members suffer from laryngeal obstruction caused by bilateral vocal cord paralysis, outer and middle ear deformity with conductive and sensorineural hearing loss, facial dysmorphisms, and underdeveloped shoulder musculature. The affected female members only have middle ear deformity and hearing loss. The pedigree is suggestive of an X-linked recessive inheritance pattern. SNP-array revealed a deletion and duplication on Xq28 in the affected family members. A possible aetiology is a neurocristopathy with most symptoms expressed in structures derived from branchial arches.
