To the Editor: Concerning F. Silverman's comments (Amer J Dis Child 109:392 (May) 1965), on "Why Did Hephaestus Limp?" I believe a short comment should be appended.
Diastrophic dwarfism is autosomal recessive as evidenced by numerous pedigrees in which the parents have not been involved. There have been affected siblings and the consanguinity rate among the parents has been on the order of about 20%. It was noted that Hephaestus had two affected children and, therefore, one would question the diagnosis of diastrophic dwarfism unless Hephaestus' consort was a heterozygote for the condition. However, judging from the proclivities of most of these gods, I imagine it is not unlikely that Hephaestus might have decided to keep it in the family.
