Lethal arthrogryposis with anterior horn cell disease.
Fifteen infants (11 families) with lethal arthrogryposis and anterior horn motor neuron loss are described. The clinical presentation was the fetal akinesia deformation sequence (FADS) with multiple contractures and facial anomalies. At autopsy neurogenic muscular atrophy was present in all infants. The spinal cord showed a paucity of anterior horn motor neurons in the 12 infants studied. Both male and female infants were affected. Nine cases were sporadic, whereas in two families there were three affected cases. Consanguinity between the parents was reported in one family with one affected child. This and the recurrence of the condition speak for autosomal recessive inheritance. Detailed neuropathological examination and documentation of the clinical features are needed for a better delineation of and genetic counseling for perinatally lethal arthrogryposis.
