The relationship between these two syndromes is discussed in the light of the present cases and others in published reports.

Similar infants were described by Lazjuk et all' who drew attention to reports in the Czech literature,12 and following a review of all known cases they suggested that the constellation of signs be called the Neu-Laxova syndrome. However, the COFS syndrome, which may itself be heterogeneous, and the Neu-Laxova syndrome have sufficient features in common for some authors to consider them to be possibly part of the same entity.7 13 In the absence of a specific biochemical or other marker it is impossible to resolve this diagnostic hetero- AM geneity and in this report we describe three further cases, two of whom appear to conform most closely to the COFS group, and one of whom has features common to both the COFS and Neu-Laxova syndromes.
