Metacarpophalangeal pattern profile analysis in Brachmann‐de Lange syndrome

We analyzed the metacarpophalangeal pattern profile (MCPP) of 19 individuals with Brachmann‐de Lange syndrome (BDLS) and calculated a mean syndrome profile. Fourteen of 19 individuals with BDLS had significant positive correlations which indicated clinical homogeneity. Discriminant analysis of individuals with BDLS compared with a sample of normal individuals produced a correct classification rate of 100% based on a function of 2 MCPP variables that may provide a useful tool for assisting in the diagnosis of BDLS. An average pattern variability index calculated for the BDLS patients was 1.9 indicating an abnormal hand pattern in this syndrome. © 1993 Wiley‐Liss, Inc.
