JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 416 OP 418 DO 10.1136/jmg.20.6.416 VO 20 IS 6 A1 Wilson, W G A1 Kennaugh, J M A1 Kugler, J P A1 Reynolds, J F YR 1983 UL http://jmg.bmj.com/content/20/6/416.abstract AB Two brothers with developmental delay and unusual cranial configurations were found to have agenesis of the corpus callosum (ACC) by CT scan. Six published families in which ACC occurred in the absence of extracranial malformations are reviewed. No single mode of inheritance can account for all of these familial cases. This family illustrates the value of CT scanning in evaluating children with developmental delay.
