Craniofacial pattern profile (CFPP) evaluation of facial dysmorphology in a familial syndrome with corneal anesthesia and multiple congenital anomalies.
Roentgencephalometric findings are presented for a family with an unusual facial morphology. Twenty measurements defining the size and shape of major anatomic areas of the head and face were taken. The measurements were transformed into Z-scores. Using the sigma z (i.e., standard deviation of the Z-scores) value, an estimate of craniofacial pattern deviation from the norms was made for each family member. All members of this family have highly aberrant, i.e., dysmorphic, craniofacial pattern profiles. Familial as well as syndromic craniofacial similarities vs. dissimilarities between Z-score values of pairs of family members were assessed by the Pearson's correlation coefficient rz. Results of correlation coefficients demonstrate a high level (far in excess of the expected value of rz 0.50) of craniofacial pattern profile (CFPP) similarity between sibs and between sibs and their mother. This strongly suggests that the two sibs and their mothers are the carrier of the same genetic syndrome.
