Microcephaly-lymphoedema-chorioretinal dysplasia: three cases to delineate the facial phenotype and review of the literature.

Microcephaly-lymphoedema-chorioretinal dysplasia (MIM 152950) has been described as a distinct clinical entity. The mode of inheritance is uncertain, but male to male transmission has been observed supporting autosomal dominant inheritance. A characteristic facial phenotype has recently been suggested. We report three isolated male patients with this condition who have all of the major features and share a distinct facial appearance with upslanting palpebral fissures, a broad nose with rounded tip, anteverted nares, long philtrum with thin upper lip, pointed chin and prominent ears. The clinical features in our patients support the hypothesis of a characteristic facial phenotype in this syndrome.
