BOWEN-CONRADI SYNDROME - HIGHLY LETHAL AUTOSOMAL RECESSIVE SYNDROME OF MICROCEPHALY, MICROGNATHIA, LOW BIRTH-WEIGHT, AND JOINT DEFORMITIES

This paper describes six Hutterite children from five families who appear to have been affected by the same syndrome that was described in two brothers by Bowen and Conradi. These additional cases confirm that the major features of the syndrome include proportionate intrauterine growth retardation, microcephaly, micrognathia, a prominent nose, rocker-bottom feet, joint limitation, and failure to thrive, with death within the first year of life. Bowen-Conradi syndrome is an autosomal recessive trait and pedigree records show that all six families now known are related to each other through two couples born in the late 1700s but that there are additional earlier possible sources of the responsible gene. The differential diagnosis of this syndrome is discussed.
