Mutations in the Pre-Replication Complex cause Meier-Gorlin syndrome

Meier-Gorlin syndrome (ear, patella, short stature syndrome) is an autosomal recessive primordial dwarfism syndrome characterised by absent/hypoplastic patellae and markedly small ears1-3. Both pre and post-natal growth are impaired in this disorder and although microcephaly is often evident, intell...

Descripción
Sumario:Meier-Gorlin syndrome (ear, patella, short stature syndrome) is an autosomal recessive primordial dwarfism syndrome characterised by absent/hypoplastic patellae and markedly small ears1-3. Both pre and post-natal growth are impaired in this disorder and although microcephaly is often evident, intellect is usually normal. We report here that this disorder shows marked locus heterogeneity and we identify mutations in five separate genes: ORC1, ORC4, ORC6, CDT1 and CDC6. All encode components of the pre-replication complex, implicating defects in replication licensing as the cause of a genetic syndrome with distinct developmental abnormalities.
