Purpose: We studied an Italian family affected by the autosomal dominant form of microcephaly and chorioretinal degeneration that was characterized by various degrees of clinical expression. Methods: An ophthalmologic examination, including visual acuity, visual field testing, an electroretinogram, and fundus photography, and a neurologic examination, including neurodevelopmental status and neuroimaging studies, were performed for all subjects. Skeletal radiography, chromosome studies, and serologic investigations were also performed. Results: In this family, only two of the six affected members had an association of microcephaly, myopia, and chorioretinal degeneration. The other family members showed microcephaly, slight mental retardation, and short stature, but not chorioretinopathy. Conclusions: The significant finding in members from this dominant pedigree of microcephaly was the association of short stature and high myopia, heretofore seen only in families with recessive microcephaly. These findings could be useful for genetic counseling in the apparently isolated forms of microcephaly with chorioretinopathy.

Abstract

Purpose: We studied an Italian family affected by the autosomal dominant form of microcephaly and chorioretinal degeneration that was characterized by various degrees of clinical expression. Methods: An ophthalmologic examination, including visual acuity, visual field testing, an electroretinogram, and fundus photography, and a neurologic examination, including neurodevelopmental status and neuroimaging studies, were performed for all subjects. Skeletal radiography, chromosome studies, and serologic investigations were also performed. Results: In this family, only two of the six affected members had an association of microcephaly, myopia, and chorioretinal degeneration. The other family members showed microcephaly, slight mental retardation, and short stature, but not chorioretinopathy. Conclusions: The significant finding in members from this dominant pedigree of microcephaly was the association of short stature and high myopia, heretofore seen only in families with recessive microcephaly. These findings could be useful for genetic counseling in the apparently isolated forms of microcephaly with chorioretinopathy.
