Description : Of the 7 children of parents related as half first cousins, 1 boy died during a convulsion
at age 2 months and the other 6, born between 1925 and 1935, had severe mental retardation
and extensive calcification of the choroid plexus (Lott et al., 1979). Strabismus,
hyperactive deep tendon reflexes, Babinski sign, and lalling speech were other clinical
features. ('Lalling speech,' an archaic expression, was used by Friedman and Roy (1944)
in first reporting this family.) CSF protein concentration was 2-3 times normal. Neuropathologic
studies were done in 1 sib, who died at age 26 years of cardiovascular collapse, possibly
due to an abrupt withdrawal of corticosteroids given for bronchial asthma; autopsy
showed severe bilateral adrenal atrophy. Small subcortical heterotopias and atrophy
of the choroid plexus with encasement by glial fibrils were found. Lott et al. (1979)
postulated a hereditary disorder of the choroid plexus. In the 1 patient studied,
the choroid plexus failed to take up radiolabeled (99m)Tc-pertechnetate. The only
other report of this disorder seems to be that by Singh et al. (1993). Three sibs
in a Saudi family had mental retardation, calcification of the choroid plexus, and
increased CSF protein. *FIELD* RF 1. Friedman, A. P.; Roy, J. E.: An unusual familial
