Implication

Registry study reveals a malformation spectrum spanning Potter syndrome to sirenomelia in newborns, suggesting variable caudal mesoderm damage as a shared developmental mechanism.

Key Points

To characterize the spectrum, clinical associations, and epidemiological patterns of congenital malformations spanning Potter syndrome and sirenomelia.
Screened 6,168 malformed infants recorded in the Swedish Register of Congenital Malformations from approximately 550,000 births between 1965 and 1971.
Identified and analyzed clinical characteristics and temporal-geographic patterns among 73 infants displaying anomalies along the Potter syndrome–sirenomelia spectrum.
Identified 73 cases among approximately 550,000 births (incidence of 1 in 7,500 births), exhibiting a continuous phenotypic series from typical Potter syndrome to sirenomelia.
Observed that pulmonary hypoplasia and Potter face were not solely secondary to oligohydramnios, while central nervous system defects, facial clefts, and congenital heart defects occurred less frequently than in other multiply malformed infants.
Detected an apparent temporal increase in incidence, clustering in central Sweden, and a higher-than-expected rate of conceptions beginning in summertime, without an identified exogenous cause.
