É relatada a ocorrência de formas clínicas diversas de craniostenose em gêmeos de sexo diferente. A menina apresentava obliteração completa da sutura coronaria e dos dois terços anteriores da sutura sagital; no menino a sutura sagital era a única afetada. O estudo genético mostrou que a craniostenose independe de aberrações cromossômicas, indicando ser transmitida por gens recessivos raros de natureza autossômica.
The occurrence of two clinical forms of craniostenosis in twins of different sex born to consanguineous parents is reported. The girl showed total fusion of the coronary suture; in the boy sagittal suture was the only one involved. The genetic study showed that the craniostenosis was not associated with chromosomal anomalies and was related to rare auto-somic recessive gens.
