We report on a Spanish child with clinical manifestations suggestive of aminopterin syndrome sine aminopterin (ASSA), having unusual hair pattern, syndactyly of fingers and toes, low-set thumbs, high-arched palate, and mild developmental delay. However, he does not show other characteristic features of ASSA such as ossification defects of the cranium, microcephaly, hypertelorism, cryptorchidism, or growth retardation. Differences from and similarities with Juberg-Hayward syndrome are discussed. Because few patients have been reported so far it is difficult to distinguish between these two conditions, and it may be that they are variants of the same nosological entity. Consanguinity of parents in this family supports autosomal recessive inheritance of ASSA.

We report on a 4-year-old boy with craniometadiaphyseal dysplasia (CMDD), wormian bone type. Component manifestations include a large head with prominent forehead, skull changes showing multiple wormian bones, wide long tubular bones without the usual metaphyseal flare, wide and short tubular bones without the normal diaphyseal constriction, and wide ribs and clavicles. In addition to these findings, the propositus, his brother, his father, and a paternal aunt all have parietal protuberances, which seem not related to CMDD. Parental consanguineity supports the autosomal recessive transmission of the condition.
