Rajab et al.

(2009) described 2 interrelated Omani families in which 8 children had brain calcifications of basal ganglia and cortex, mild developmental delay, poor school performance, microcephaly, growth delay, and osteopenia. The widespread brain calcifications were similar to those in Aicardi-Goutieres syndrome (225750) and Coats plus syndrome (612199). Rajab et al. (2009) suggested that the disorder in the Omani families represents a new variant or possibly a new disorder of inherited brain calcification.
