Smallest critical region for microcephaly in a patient with mosaic ring
... Microcephaly is relatively common among developmentally delayed children. Four single etiologic genes have been identified. Microcephaly is also associated with at least 7 loci (Kinsman and Johnston, 2011) and is commonly observed in ring chromosome 13, or r(13) (Brandt et al., 1992; Bedoyan et al., ...
