Johanson-Blizzard syndrome in a large inbred kindred with three involved members

Abstract

An infant with aplastic alae nasi, imperforate anus, focal aplasia cutis over the fontanels, microcephaly, and mental retardation is presented as an example of the Johanson-Blizzard syndrome. The infant failed to thrive and had evidence of malabsorption. He died at 4 months of age. The occurrence of extensive consanguinity in his family and the occurrence of two other members of the kindred with a similar syndrome indicate that this disorder is transmitted by an autosomal recessive gene.
