Dubowitz syndrome: review of 141 cases including 36 previously unreported patients.
We review clinical information on 141 individuals with Dubowitz syndrome, 105 reported since 1965, and 36 previously unreported. We define the Dubowitz syndrome phenotype on the basis of clinical descriptions. The facial appearance is characteristic and present in most patients with Dubowitz syndrome. The phenotypic spectrum is quite variable and ranges from normal growth and head circumference with mild psychomotor retardation and lack of eczema to a condition of severe growth retardation, mental retardation, microcephaly, and eczema. Overall, the condition may involve the cutaneous, ocular, dental, digestive, musculoskeletal, urogenital, cardiovascular, neurological, hematological, and immune systems. Characteristic behavior patterns which have not been cited previously are present in our cases; most patients are hyperactive, shy, hate crowds, and like music, rhythm, and vibrations from music speakers, tape recorders, or transmitted through floors. Dubowitz syndrome is an autosomal recessive disorder with possibly increased frequency of parental consanguinity. Heterogeneity cannot be excluded at this time.
