Abstract
THE 1964 epidemic of rubella resulted in the birth of many abnormal infants. While examining these infants for the clinical signs of rubella embryopathy we observed multiple unusual dermatoglyphic findings: an increased incidence of simian lines; bilateral distal axial triradii; and radial loops on digits other than the second finger. These findings are relatively rare in the normal population.1 Our interest was aroused because the unusual dermatoglyphic patterns appeared to develop in these unrelated infants with diverse genetic backgrounds when they were affected in utero by the rubella virus. A dermatoglyphic survey of the infants was then undertaken to test . . .
