Familial microcephaly with severe neurological deficits: a description of five affected siblings

Abstract

Autosomal recessive microcephaly is usually characterized by normal developmental milestones and minor neurological deficits. In this report, we describe five siblings in one family with marked microcephaly, intractable seizures, quadriplegia and profound mental retardation. The recurrence risk of microcephaly when associated with devastating neurological deficits, as exemplified by this family, may be high and in such cases, the role of appropriate genetic counseling is of utmost importance.
