Data on the occurrence of poly- and syndactylies among 64793 newborn children were collected from the hospital records of two different Swedish hospitals, one being located in the North and the other in South Sweden. Frequency estimates are given for the different types of anomalies and the families of 35 probands were studied.

Some pedigrees were compatible with dominant transmission of the traits, while in others the mode of inheritance is irregular. There was no evidence for Y-linked syndactyly. In several cases it was found that a proband with Polydactyly had relatives with syndactyly and vice versa. Some pedigrees included also individuals with reductions of phalanges and fingers.
